How are negatively charged beta particles emitted from a positively charged nucleus during nuclear decay?
During nuclear decay when a beta - particle (a high energy electron coming from the decay event) leaves the nucleus, the action is the result of the transformation of a neutron into a proton and an electron (the beta - particle).. Got links if you want them. They are to related articles posted by… our friends at Wikipedia, where knowledge is free.. Note: there is a bit more to beta decay than was mentioned here, but enough was presented to answer the question. Certainly it is hoped that the links will extend knowledge about as far as the average reader may wish to go. ( Full Answer )
A beta particle is either an electron or a positron emitted by an atomic nucleus in beta decay, which is a type of radioactive decay. The phenomenon of beta decay involves a change within the atomic nucleus of an atom. One of two reactions may occur, and they involve the change of a neutron into… a proton, or a proton into a neutron. When a neutron changes into a proton, we call that beta minus decay. The change of a proton into a neutron is called beta plus decay. In beta minus decay, an electron is ejected from the nucleus, and in beta plus decay, a positron is ejected from the nucleus.

Of an electron and a proton and a gamma ray and an alpha particle and a beta particle which has a positive charge of two?
Answer . The alpha particle (which is a helium nucleus), is composed of two protons and two neutrons. The two protons give it a charge of +2..
A beta particle is two particles emitted in the form of radioactive decay called beta decay. It is either an electron and an electron anti neutrino , which is emitted in beta - decay, or a positron and an electron neutrino , which is emitted in beta + decay. Use the link below to the related… question on beta decay to help you sort it out. ( Full Answer )
There is a difference between beta emitters and beta particles. In situations where an atomic nucleus exhibits nuclear instability due to too many neutrons for the number of protons or vice versa, that nucleus may undergo beta decay. It the decay event occurs, that atom is considered a beta emitter.… The emitted particle is the beta particle. That's the difference. (There are two different beta particles, so check the articles on beta decay to get the scoop.) ( Full Answer )
How is it possible that negatively charged beta particles are emitted from a positively charged nucleus during nuclear decay?
An electron (negative particle) and an electronneutrino (neutral particle) are released when a neutron (neutral particle) changes into a proton (positive particle) therefore in order for neutral charge to createa positive particle it also has to create a negative particle tobalance it out. As… a significant amount of binding energy is released, the electronis ejected at high velocity as betaradiation while the much more massive nucleus containing the newlycreated proton recoils with very lowvelocity . The neutrino having almost no mass is ejected atalmost the speed of light, but is nearly impossible to detectexcept by implication from the "missing momentum". Basically beta particles are ejected from the nucleus by conservation of momentum before and after the decay event. ( Full Answer )
Beta Particles have a negative charge,In Beta decay a neutron changes into a proton and a beta particle, an electron.
The sign of the charge depends if it's a beta-minus particle (an electron) or a beta-plus particle (a positron, or anti-electron). The former is negative, but the latter is positive. Generally, when we say "beta particle," we mean "beta-minus particle," but this is not always the case! For an elemen…t that decays via beta, check the locations on the periodic table (or better yet, the table of nuclides!) of the parent and daughter atoms. If the atomic number of a nucleus increased by one when undergoing beta decay (it now has an extra proton), it underwent beta-minus decay. If the atomic number decreased by one, it underwent beta-plus decay. Important note: we have just discussed the sign of the beta particle's charge, not the charge itself. The charge, in SI units, is 1.6022 x 10^-19 Coulombs. This quantity is, again, negative or positive depending on whether the particle in question is a beta-minus or beta-plus. ( Full Answer )
The emission of a Beta particle has the effect of decaying aneutron into a proton and an electron. This increases the atomicnumber and the electron is ejected energetically. The number ofneutrons are decreased by one and the number of protons increase byone, changing the atom to a different element.… ( Full Answer )
No, beta decay isn't the same as a beta particle, but a beta particle is emitted in beta decay.. There are two kinds of beta decay, and they are beta minus and beta plus decay. In these decay events, an electron and a positron (anti-electron) will be emitted from a nucleus, respectively. Beta decay… is the event, and the beta particle is a product of the event.

A alpha particle is a helium-4, written 2 4 He, nucleus, and it is composed of a pair of protons and a pair of neutrons fused together. It's charge is +2. A beta particle could be either a beta + particle, which is a positron, or a beta - particle, which is an electron. The electron (beta -) has a… charge of -1, and the positron (beta +) has a charge of +1.. In summary, the alpha is +2, the beta minus is -1, and the beta plus is +1. ( Full Answer )
Electrons are identical to beta particle since beta particles ARE electrons with high energy content that can ionize atoms it come across.
A beta particle has an electric charge of -1 because beta particles are both lightweight and fast moving, they have a greater penetrating power than alpha particles.
Alpha particles are positively charged helium nuclei while beta particle are negatively charged electrons . Alpha particle have 4u mass while beta particles have zero mass.
Beta particle has a negative charge -1 and the relative mass is 0.00055 the nature is electron (produced by nuclear changes) the range in the air is a few metres Its stopped by aluminium foil the deflection by electrical field
Beta particle symbols: e- or Î²- or B- (electrons) or e+ or Î²+ or B+ (positrons). If the - or + sign is omitted, assume that the beta particles are electrons. The Greek beta character is usually preferred, but a B is acceptable if Greek fonts are not available.
a slanted P that looks like a B but is thinner and has a longer "leg"
Why does an alpha particle have twice the electric charge of a beta particle but deflects less than a beta in a magnetic field?
An alpha particle, which is a 2 4 He nucleus, has a mass of 4 and a charge of +2. A beta particle has a charge of +1 or -1, depending on whether it is a positron (beta +) or an electron (beta -). It's mass is minuscule compared to the alpha particle, and it will undergo a comparatively huge deflec…tion in the same field as an alpha particle would.. Though the alpha particle has twice the charge as a beta particle, it has several thousand times the mass of that beta particle. As it is so much more massive than the beta particle, its inertia will be much more difficult to overcome even though it has twice the charge. ( Full Answer )
Betaminus (Î²-) particles are the same as electrons . Betaplus (Î²+) particles are the same a positrons
Beta particles are negatively charged are electrons and have -1 unit charge and 0 mass. They are very dangerous and have high penetrating power.
A beta particle is an electron or a positron, with a charge of -1 or +1, and a mass of about 1/1836 of a proton. An alpha particle, on the other hand is a helium nucleus, with a charge of +2, and a mass of two protons and two neutrons. The beta particle has more penetration ability than the alpha pa…rticle, but the alpha particle is more biologically dangerous when in close proximity to sensitive tissue, such as when inhaled into the lungs.

Beta particle is made up of an electron particle of negative charge. However, if said positive beta particle, then it is made up of positron that is equivalent to electron but with positive charge. For more information, refer to the related question listed below.
NO about 0.99 the speed of light howeaver they are electrons ( or positrons ) so exibit wave properties so there velocity cannot be mesured due to uncirtanty
Its size mass and charge is similar to electron about 1836 times less than a proton.
Beta particles can be positive or negative. A negative beta particle is a fast moving electron. A positive beta particle is a positron. Most beta decay is negative.
It's a free electron (or positron). It also consists of fast moving electrons that are emitted from unstable nuclei.
IN the so-called "beta decay", an atom will emit either electrons, or anti-electrons (positrons), but the most common case is that it simply emits electrons.
Beta particles are usually described as a ray of electrons ( or negatively charged particles).
The gamma particle's symbol is the lowercase Greek gamma, the velar, which looks like a lower case western v, but the base has a narrow loop, and the left top has a curved serif. In print, it looks like a Y, shifted down as if it were a lower case letter with a descender. We can't represent it he…re on Answers.com, but the Related Link below will take you to WikiPedia where you can see a representation of it. The charge of a gamma particle is that of the photon, which is zero. ( Full Answer )
The atomic nucleus can emit beta particles (beta radiation). A neutron emits a beta particle when it decays into a proton, and anti-neutrino, and an electron (which becomes the beta particle).
How do the electric charges of alpha particles beta particles and gamma rays differ from each other?
An alpha particle has a 2+ charge. A beta particle can have a 1+ or a 1- charge, and gamma particles have no charge.
From Physics Forums The alpha particle has a 2+ charge, beta has 1- charge, and the gamma is neutral (no charge). The beta particle could also have a 1+ charge if it undergoes positron emission [a proton turns into a neutron and a positron (the "anti-electron")]
Is it possible that negatively charged beta particles are emitted from a positively charged nucleus during nuclear decay?
Yes, it is. This occurs in nuclei with a significant excess of neutrons toprotons. To reduce this excess the weak force sometimes changes aneutron to a proton, which ejects an electron (beta particle) andan electron neutrino. This process makes the nucleus even morepositively charged (thus conser…ving charge). ( Full Answer )
because the total enegy of the decay is carried by beta particle and the nutrino.
These particles are more dangerous than alpha rays. They are negatively charged electrons . They have -1 unit charge and zero mass.
Subatomic particle Electron Proton Neutron . Symboland charge . e - negative charge . p + Positively charged . n Neutral charge .
No. Beta - particles, electrons, have a charge of -1, and beta + particles, positrons, have a charge of +1. The alpha particle has a charge of +2.
When a positron is emitted a proton is converted into a neutron. Therefore the new nucleus will have a positive charge that is one less than its previous charge.
Does a alpha particle have a negative charge and is it heavier than the positive charged beta particle?
The question is partially in error. The alpha particle has a +2 charge and is about 7200 times heavier than the negatively charged beta particle. The reverse is only true with antimatter, but only inasmuch as the alpha particle would still be heavier.
The particle that carries the positive charge (a proton) is much more massive than the particle that carries the negative charge (an electron) The charges are equal in magnitude though of opposite polarity.
Beta particles, from beta - decay, have a charge of -1. Beta particles, from beta + decay, have a charge of +1. Alpha particles have a charge of +2.
Beta radiation is a negatively charged electron which both penetrates and ionizes fairly well. Alpha is a helium nucleus with 2 protons and 2 neutrons (so a +2 charge) and is very ionizing but not very penetrating.
Gamma rays don't carry charge, BUT beta particles do - so a neutron must become a proton.
An alpha particle is a positively charged particle composed of two protons and two neutrons. Beta particles are emitted from nuclei undergoing radioactive decay, and are either electrons with a negative charge, or positrons with a positive charge.
I'm guessing that this is referring to the electron, since that is what, essentially, a beta particle is.
A beta particle is an electron, and electrons are negative. You're probably thinking of a positron, which has the same mass as an electron but the opposite charge.
The beta particle is formed when a neutron decays into a proton and electron. So the number of protons increases, causing an increase in the charge of the nucleus by 1, and a very tiny decrease in mass.
Beta particles can be both positively AND negatively charged; they are either high-energy, high-speed electrons (negative standard charge) or positrons (positive standard charge) emitted by certain types of radioactive nuclei such as potassium-40 ( 40 K)
