Answer:
C) After reacting, each ion has a stable octet.
Explanation:
Atoms bond to gain stability and to do that they must fill in their outer energy shell with 8 electrons, which we call an octet. In the case of sodium and chlorine, the sodium atom donates one electron to chlorine. When an atom loses an electron, the protons outnumber the electrons, so they become positively charged. This means it will become a cation.
