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

A)Sodium loses a negative electron when forming chemical bonds

Answer 2

Answer: Option (A) is the correct answer.

Step-by-step 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.
