It depends on what caused the gamma event in the first place.
Strictly speaking, gamma radiation is caused by the de-excitation of the nucleus, so the atomic number (and Atomic Mass) does not change during a gamma event.
However, the gamma event is usually precipitated by some other event, such as a beta or alpha decay that does change the configuration of the nucleus. An alpha event reduces the atomic number by 2 (and reduces the Atomic Mass by 4), while the beta event increases the atomic number by 1 (and does not change the atomic mass very much).
Its actually more complex than that, but the answer to the original question is that nothing really happens to the atomic number during a gamma event.

Energy/radiation
the atomic structure of an isotope is cyristal like
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
Well all Isotopes have the same atomic number so if you have the element the atomic number of an element with that same isotope is that same atomic number.
The atomic mass of the most stable isotope of Roentgenium is 281. This most stable isotope decays in around 36seconds. Oddly, it's most stable isotope has the same atomic mass as the most stable isotope of the element before: Darmstadtium.
Energy/radiation
When the nucleus releases a beta minus particle the atomic number increase with 1.When the nucleus releases a beta plus particle the atomic number decrease with 1.
the atomic structure of an isotope is cyristal like
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
Subtract the atomic number of the isotope from its atomic mass number to obtain the number of neutrons in an isotope.
Atomic Mass (of an isotope) - number of protons (of an isotope) = number of neutrons (of an isotope)
nothing, but another isotope with the same atomic mass is formed
The atomic number of an isotope is always identical to every other isotope, otherwise, it would form a separate element.
Well all Isotopes have the same atomic number so if you have the element the atomic number of an element with that same isotope is that same atomic number.
153 neutrons in the most stable isotope Number of neutrons = Atomic mass of an isotope - atomic number. Atomic mass of the most stable isotope of Cf is 251. Atomic number of Cf is 98.
A radioactive isotope of an element
There is no such isotope. The highest atomic number is 118. The question is erroneous. The isotope platinum-190 has the atomic number 78, the mass number 190 and the atomic mass 189,959 932(6).
