How is the atomic number changed by gamma decay?
There is no change in atomic number with the emission of gamma radiation. Unlike alpha or beta radiation, it does not have any kind of particles. It's emission results only when an excited nuclei goes to an unexcited state by emitting these.
When an unstable nucleus produces an beta particle by how many units does the atomic number of the nucleus change?
The atomic number decreases by one for each beta particle
What are the 4 types of radiation and what does each type do to the nucleus?
Usually with the '4 types of radiation' it is referred to:- alpha radiation (emission of an alpha particle = a helium nucleus = 2 neutrons + 2 protons):Hence for the emitting nucleus the mass number decreases by 4 and the atomic number by 2.- beta-minus radiation (emission of a beta- particle = an electron)Hence for the emitting nucleus the mass number remains the same and the atomic number increases by 1 (a neutron decays into a proton and beta- radiation)- beta-plus radiation (emission of a beta+ particle = a positron)Hence for the emitting nucleus the mass number remains the same and the atomic number decreases by 1 (under the addition of energy a proton decays into a neutron and a positron)- gamma radiation (emission of high energetic photons)The emitting nucleus doesn't change its mass number and atomic number,but it jumps from a higher energy level to a lower energy level.
What is the nuclear reaction for the transformation of Cs-137 into Ba-137?
Beta Emission as there is no change in the atomic mass of the atom but there is an increase in the atomic no. of the atom.
Which sub-atomic particle cannot change?
The sub-atomic particles does not change is electron. Electron not remains negatively charged but its mass remains the same too.
What atomic particle has a positive change?
Protons
How do positron emission and electron capture change an atom?
After positron emission or electron capture the atomic number is decreased with one.

What happens to the atomic number of an element if it emits 1 alpha particle and 3 beta particles?
It depends on whether the beta decay is beta- or beta+. The alpha emission reduces the atomic number by 2. Beta- increases the atomic number by 1 while beta+ decreases the atomic number by 1. You do the math.
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.
When an unstable nucleus produces an beta particle by how many units does the atomic number of the nucleus change?
The atomic number decreases by one for each beta particle
How does the emission of an alpha particle change the mass number of the parent nuclide?
The mass number decrease with 4.
When a beta particle is emitted does the mass number of the isotope remains unchanged?
With the ejection of a beta particle (electron), there is a minute loss of mass. Electrons have very low mass. The atomic number increases though as a neutron is transformed into a proton. A antineutrino is also ejected. In a similar process, positron emission also called beta decay,- a positron is emitted and a proton is transformed into a neutron, the atomic number decreases. A neutrino is also ejected.

What is the change in the atomic number when the atom emits an alpha particle?
The atomic number will decrease by 2, the number of protons in the emitted alpha particle. An alpha particle is a helium-4 nuclei with two protons and two neutrons.

Beta Emission as there is no change in the atomic mass of the atom but there is an increase in the atomic no. of the atom.
