How is the atomic number of a nucleus change is it by alpha decay or beta decay or gamma decay?
Alpha decay decreases the atomic number by two. Beta- decay increases the atomic number by one. Beta+ decay decreases the atomic number by one. Gamma decay does not change the atomic number. However, gamma decay is often incidental to a precipitating alpha or beta event that upsets the energy equilibrium in the nucleus, so the two are not unrelated.
What is the radioactive decay of an atom resulting in the decrease in the atomic number with no charge in the atomic mass called?
It is called beta decay. there are two types: 1) posive beta decay in which atomic number decreases. 2) negative beta decay in which atomic number increases.
If i have Barium with an atomic number of 56 and an atomic mass of 137 and it undergoes alpha decay once and then beta minus decay what is my finishing atomic number and mass?
When barium (atomic number 56) undergoes alpha decay, it loses 2 protons and 2 neutrons, resulting in an atomic number of 54 and an atomic mass of 133 (56 - 2 = 54, 137 - 4 = 133). After that, during beta minus decay, a neutron is converted into a proton, which increases the atomic number by 1, leading to an atomic number of 55 while the atomic mass remains 133. Therefore, the final atomic number is 55 and the atomic mass is 133.
How do you find the isotope in alpha and beta decay?
In Beta- decay, a neutron is converted into a proton, and an electron and electron anti-neutrino are emitted. The Atomic Number goes up by one, and the Atomic Mass Number stays the same. For instance, 6C14 becomes 7N14 plus one electron and one electron anti-neutrino. In Beta+ decay, a proton is converted into a neutron, and a positron and electron neutrino is emitted. The Atomic Number goes down by one, and the Atomic Mass Number stays the same. For instance, 6C11 becomes 5B11 plus one positron and one electron neutrino. Isotopes that decay by Beta+ decay also tend to decay by Electron Capture, a process where an inner K shell electron is absorbed by the nucleus, changing a proton into a neutron and emitting a neutrino. The isotope conversion process would be the same as for Beta+, above. In Alpha decay, a Helium nucleus (two protons and two neutrons) are emitted. The Atomic Number goes down by two, and the Atomic Mass Number goes down by four. For instance, 92U238 becomes 90Th234 plus one Helium nucleus
What is a good explanation why the atomic number stays the same during beta decay?
To my knowledge (and I stand to be corrected on this), the atomic number of an element does not stay the same after beta decay but increases or decreases by 1 depending on the direction of the decay; if a neutron becomes a proton, the atomic number changes by +1; if a proton becomes a neutron, the atomic number changes by -1.

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.
What changes in atomic number and mass number occur in beta emission?
Electron (beta minus) decay: the atomic mass remain approx. constant, the atomic number will be greater with 1 Positron (beta plus) and electron capture decay: the atomic mass remain approx. constant, the atomic number decrease with 1 Double beta decay: the atomic mass remain approx. constant, the atomic number will be greater with 2
How is the atomic number of a nucleus changed by beta decay?
An alpha particle is essentially a helium atomic nucleus with 2 protons and 2 neutrons. An alpha particle decay will result in the loss of 2 protons and 2 neutrons. Because mass number is the sum of protons and neutrons, an alpha decay will reduce the mass number by 4, (and the atomic number by 2).

How do the three forms of radioactivity change the atomic number?
They don't. Only atoms really have an atomic number, which is the number of protons in each atom, so when that number changes as in alpha and beta radiation the atom no longer has a neutral charge and becomes an ion. Gamma radiation is an electro-magnetic wave so it doesn't affect the atomic number and the particle is still an atom. Hypothetically, nd I'm not sure it's possible, alpha radiation would reduce the atomic number by 2, beta would reduce it by 1 and gamma doesn't reduce it at all anyway.

How does beta radiation affect the nucleus?
The end result of beta- decay is that a neutron is converted into a proton, increasing the atomic number while keeping the atomic mass number the same. The end result of beta+ decay is that a proton is converted into a neutron, decreasing the atomic number while keeping the atomic mass number the same.
When uranium-238 atomic number 92 decays by emitting an alpha particle it becomes?
When uranium-238 (atomic number 92) decays by emitting an alpha particle, it transforms into thorium-234 (atomic number 90) because an alpha particle contains two protons and two neutrons, reducing the atomic number by two.
How does alpha beta and gamma decay change the nucleus?
Gamma decay is the release of energy, but does not in itself change the nucleas Alpha decay is the loss of 2 protrons and 2 neutrons, lowering the atomic number by 2 and mass number by 4 Beta can occur as a result of a neutron turning into a protron, raising the atomic number by 1 and charge by 1
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.
