How do the electric charges of alpha particles beta particles and gamma rays differ from each other?
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")]
What does a radioactive element decay to form?
A radioactive element will decay to form different elements or isotopes through the emission of radiation such as alpha particles, beta particles, or gamma rays. Decay products typically have different atomic numbers and mass numbers than the original element.
What are the two types of radioactive decay?
It can be argued that they all can: Alpha is emission of helium nucleus - a loss of four nucleons. Clearly a new nuclide. Beta decay converts a proton into a neutron or vice-versa, with subsequent emission of a positron or electron, respectively (plus a neutrino). This decay maintains total mass number as one nucleon turns into another, but the proton (or atomic) number changes by +/- 1. This therefore produces a different nuclide. Gamma is a bit different as it's usually emitted along with alpha or beta decay. However, there are many cases of "isomers." These are unstable nuclei that emit gamma radiation, known (in this case) as isomeric transition (IT). IT is distinguished from "normal" gamma emission by the relative stability of the unstable nuclide - usually referred to as a metastable nuclide. An isomer is stable enough to have its own half-life calculated. Metastable nuclides are labelled as such with an "m" following the mass number - e.g. Kr-81m, Tc-99m and In-113m. Also see this decay scheme as an example: Mo-99 (T_1/2 ~3 days) -> Tc-99m (T_1/2 ~ 6 hr) -> Tc-99 (T_1/2 2e5 yr) -> Rb-99 (stable) So I reckon the short answer is alpha, beta AND gamma.
What is a type of nuclear radiation?
Alpha - Stable Helium Nucleus without any electrons Beta - A negatively charged electron emitted from the nucleus when a neutron turns into a proton Gamma - An high energy, short wavelength Electro Magnetic Wave emitted when an unstable atom has too much energy
Are the alpha particle and helium nucleus the same thing?
Yes and no, alpha particles are a form or radiation (a helium nucleus), they are emitted from an unstable radioactive element which decays (and turns into some lighter element) by emitting the alpha particle. This form of decay is called alpha decay.
What produces Gamma rays?
Gamma rays are typically produced by the decay from high energy states of atomic nuclei, called gamma decay, but they are also created by other processes. For instance, gamma rays are also produced by secondary radiation from atmospheric interactions with cosmic ray particles. Also, rare terrestrial natural sources produce gamma rays that are not of a nuclear origin, like lightning strikes and terrestrial gamma-ray flashes. Plus, they are produced by astronomical processes where very high-energy electrons are produced that cause secondary gamma rays via bremsstrahlung, inverse Compton scattering and synchrotron radiation.
Is Thorium-234 Proactinium-234 -1 a alpha decay equation?
It's beta decay. Actually, it's beta minus decay. A neutron in the nucleus of thorium-234 undergoes beta minus decay and changes into a proton with the subsequent release of an electron, an antineutrino and some energy. The transformation of a neutron in the thorium nucleus into that proton creates another element. You'll recall that the identity of an element is determined solely by the number of protons in its nucleus. And our thorium atom has now become a protractinium-234 atom.

What is battlefield 3 alpha?
The Battlefield 3 Alpha is a early version of the final product Battlefield 3 that is used by selected individuals to test out before the "Beta" comes out. In more basic turns an early version of Battlefield 3.
What is iodine in the presence of when it turns black?
When iodine turns black, it is usually in the presence of starch. This forms a blue-black complex that is used in various chemical tests to detect the presence of starch in a substance.
What happens when the emission light turns on in a 2001 Ford Focus?
It means that one of the emission system components is malfunctioning. Could be due to some of the following reasons: dirty or inoperative PCV valve - dirty oxygen sensor - your gas tank cap may be loose or the wrong type.
Discuss with the use of examples the main differences between alpha and beta decay?
In alpha decay, an alpha particle (a helium nucleus - 2p+ and 2n0) is emitted from the nucleus of an atom. In beta decay, a neutron turns into a proton and an electron, and the electron (beta particle) is emitted from the nucleus of the atom.
What happen to atomic number and mass number of nucleus when it emits alpha particle electron and proton?
It's been awhile for me, but this is how I remember it. It is not convenient for me to look it up right at the moment, so you may want to verify this. Emitting an alpha particle (2 proton 2 neutron), atomic number would decrease by 2 and atomic mass decreases by 4.Electron emission means a neutron turns into a proton and electron, but the electron shoots out. The atomic number increases by 1 and atomic mass stays the same. Proton emission, well it loses a proton. So the atomic number decreases and mass decreases.
