Question

The electronic configuration of $N{a}^{+}$ ion is 2, 8.True or False.

• A. True
• B. False

Answer 1

The correct option is A

True

Atomic number of sodium = 11

Therefore number of electrons = 11

A positively charged ion, $N{a}^{+}$ is formed by the removal of 1 electron from a sodium atom.So, sodium ion has 11-1 = 10 electrons in it.Thus,The electronic configuration of Na⁺ ion is 2, 8.
