Question

Sodium has an atomic number of 11 and has a net charge of 0. When sodium combines with chlorine, it has a net charge of +1. Why? A) Sodium loses a negative electron when forming chemical bonds. B) Sodium gains a + proton when forming chemical bonds. C) Sodium loses a + proton when forming chemical bonds. D) Sodium shares a negative electron with chlorine.

Answer 1

Answer: Option (A) is the correct answer.

Explanation:

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

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

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.

Answer 2

A)Sodium loses a negative electron when forming chemical bonds
