A beta particle is a what created and emitted from an unstable nucleus?
NovaNet: A beta particle is simply a high speed electron.
What particle is emitted in beta radiation?
In unstable neuclei where there are 'too many' neutrons, a neutron will convert to a proton and an electron - that electron is ejected from the nucleus and is called a beta particle. It is important that we call this electron a beta particle because it is derived by radioactive disintegration in the nucleus and not an 'orbital' electron.
How does an electron move around the nucleus?
The electron has the speed of light.
A high-speed electron ejected from a nucleus durng radioactive decay is called a?
an alpha particle
What moves at a rate of speed around the nucleus of an atom?
electron
What is the release high energy electron from the nucleus?
Usually, highly electro positive atoms donate (release) electrons to convert into cations. Metals are good electron donors and a few exceptional non-metals with high negative ionization enthalpies, release electrons to gain stability and achieve nearest noble-gas configuration.
What moves at a high speed around nucleus of an atom?
This particle is the electron moving in it's orbital " around " the nucleus.
Where is the location of electrons in an atom?
Electrons are located outside the nucleus revolving around. These electrons may be named as Chemistry electrons. But when neutron within the nucleus decay, then proton and electron are produced. This electron was not already there in the nucleus. But only due to decay of neutron electron comes out. This electron may be named as Physics electron. This electron comes out at very speed and this is sensed as beta particle, named by Henry Becquerel.
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 electron neutrino (neutral particle) are released when a neutron (neutral particle) changes into a proton(positive particle) therefore in order for neutral charge to create a positive particle it also has to create a negative particle to balance it out.As a significant amount of binding energy is released, the electron is ejected at high velocity as beta radiation while the much more massive nucleus containing the newly created proton recoils with very low velocity. The neutrino having almost no mass is ejected at almost the speed of light, but is nearly impossible to detect except by implication from the "missing momentum".Basically beta particles are ejected from the nucleus by conservation of momentum before and after the decay event.
Where are elctrons found?
Electrons are found orbiting the nucleus of an atom. The reason they orbit is because the nucleus is positively charged, consisting of protons (positive) and neutrons (neutral). Of course, different charges attract. So the electrons (negative) are attracted to the positively charged nucleus, but are moving so fast that their momentum exactly cancels out the attraction to the nucleus. If the electrons were orbiting any faster, they would fly out of the atom. If they were orbiting any slower, they would eventually become part of the nucleus.
What are the three kinds of radiation?
· Alpha - a helium nucleus · Beta - a high speed electron · Gamma - an electromagnetic radiation of wavelength about 10-14 m.
Does the electromagnetic attraction of an electron to the nucleus of an atom strengthen when rotating faster like gravity?
Neither the electromagnetic or gravitational forces are affected by rotational speed.
