The numer of neutrons depends on the isotope, which, as you've noted, Xenon has several of. Pick one.
None of the isotopes of xenon ordinarily found in nature is radioactive. Like all elements, xenon has synthetic radioactive isotopes.
Xenon has eight stable naturally occuring isotopes. Besides these stable forms, there are over 40 unstable isotopes that have been studied.
Some isotopes of xenon do undergo radioactive decay to caesium.
In a nitrogen-14 atom, there are 7 neutrons, where the isotopes with mass numbers with 13 and 15, have 6 and 8 neutrons respectively.
There are 40 unstable isotopes (an element contained in xenon) that undergo radioactive decay.
Between 70 and 82 netrons.
Isotopes.
Xe has 77 neutrons.

Some isotopes of xenon do undergo radioactive decay to caesium.
The total number of protons and neutrons in the nucleus varies depending on the element, and any isotopes thereof.
In a nitrogen-14 atom, there are 7 neutrons, where the isotopes with mass numbers with 13 and 15, have 6 and 8 neutrons respectively.
Caesium and Xenon, with 36 isotopes each
There are 40 unstable isotopes (an element contained in xenon) that undergo radioactive decay.
It has mostly stable isotopes.
To accommodate the isotopes of Xenon, it is 131.29 + 6*18.998
