Answer 1

a) gain one electron

Step-by-step explanation:

When the chlorine atom reacts with the sodium atom, it creates NaCl. Sodium would be your cation and chlorine would be your anion. A sodium atom (Na) has a 1+ charge while the chlorine atom (Cl) has a 1- charge. As a result, sodium would lose a valence electron causing chlorine to gain a electron.
