The number of neutrons has no influence on the number of the atomic number. Only protons do, and they only change in nuclear chemistry.
Atomic number = Number of protons. So addition of neutron has no affect on the atomic number.Isotopes of the same element are formed by the change in neutrons.

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.
Protons = Atomic Number Electrons = Atomic Number Neutrons = Atomic Mass - Atomic Number *A note on Atomic Mass* Atomic Mass is the sum of the number of protons and neutrons in an atom. Every time you remove or add a Proton/Electron or a Neutron, you change the mass by one. *A note on Protons and Electrons* The number of Protons and Electrons in an atom is always the same. Whenever you talk about adding/removing a proton or an electron, you are by default adding/removing one of the other as well.
Gamma decay don't affect the atomic number.

If an atom looses an electron, neither the atomic mass nor atomic weight change appreciatively. If it looses a proton or neutron, both atomic mass and atomic weight decrease by one and it becomes an atom of a different element (on loss of a proton), or a different isotope of the same element (upon loss of a neutron).

Beta- decay result in an increase of atomic number by one, with no resulting change in the atomic mass number.There is a change in mass, since an electron and an electron anti-neutrino is emitted, and also because the neutron changes into a proton, but the atomic mass number, per se, does not change.
Emitting a positron, turns a proton into a neutron. So the atomic number goes down by 1, while the mass number remains the same.
In positron emission, atomic number decreases by one. That's because a proton in the nucleus of the element that is about to undergo positron emission changes into a neutron. This is beta plus decay, by the way. You'll recall that the atomic number of an element, which is that element's chemical identity, is determined solely by the number of protons in the nucleus. If we "lose" a proton because it changes into a neutron, atomic number will now decrease by one. Check out the links below to related posts.

They can vary in neutron count, which would also change the atomic mass.
Beta decay occurs when a neutron essentially spontaneously turns into a proton and emits an electron (beta particle). This results in the atomic number of the original nucleus increasing by one, but the atomic mass remains the same.
When a beta particle is emitted from a nucleus via Beta- decay, the mass number stays the same, and the atomic number goes up one, because one neutron is changed into one proton by Beta- decay.In Beta+ decay, the opposite is true. A proton is converted into a neutron, again keeping the mass number the same, but in this case reducing the atomic number by one.The ending result is different, however. In Beta-, the beta particle is an electron, while in Beta+, the beta particle is a positron.
