Answer 1

Answer:

i think neutrons is the right answer

Answer 2

Energy can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron.

Explanation:

When energy is supplied to an atom then electrons present in the lower energy shell get excited. As a result, they tend to move towards a higher energy level.

This excitation will lead a non-valence electron to become a valence electron. Whereas mass means the total number of electrons present in an atom. And, neutrons reside inside the nucleus of an atom and only nuclear reactions can make neutrons to participate in a reaction and not a chemical reaction.
