A)Sodium loses a negative electron when forming chemical bonds

Answer: Option (A) is the correct answer.

Explanation:

Atomic number of sodium is 11 and its electronic configuration is [tex]1s^{2}2s^{2}2p^{6}3s^{1}[/tex].

In order to gain stability, sodium loses one electron and hence it forms a positive ion [tex](Na^{+})[/tex].

Thus, we can conclude that when sodium combines with chlorine, it has a net charge of +1 because sodium loses a negative electron when forming chemical bonds.
