Kaitlin · Answer 1

I think the answer would be

A. They find the number of protons

Shaun Mata · Answer 2

An isotope of an element is having a different number of neutrons ex C12, C14 ...

In other words, they would have the same # of proton but different number of neutrons. So to determine the number of neutrons in an isotope of an atom, you need to subtract the atomic number from the atomic mass

For sure the answer is D
