Which two particles are found in an atoms nucleous a)neutrons
b)protons
c)isotopes
d)electrons

Option A

Option B

Explanation:

It isn't option D because electrons are on the outside of the nucleus of the atom, and it isn't option C because isotopes are usually the same elements but with different amounts of neutrons while having the same number of protons. Leaving options A and B or "neutrons and protons" as your answer and that's because neutrons and protons are always found in the center of the nucleus which also helps determine the element.

Hope this helps.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
