Question

If Protons are just as many as electrons, if I add neutrons to an atom, what is that called?

Answer 1

Answer:

You can add as many neutrons you would like to any atom as long if it's stable and whatnot. If you do add a neutron to an atom, such as Nitrogen, it still stays as Nitrogen, but its atomic mass would change.

This is referred to as an "Isotope"

Atoms of the same element, but different masses.

I hope this helps!
