Question

The element which readily forms an ionic bond has the electronic configuration.

• A. 1s${}^2$2s${}^2$2p${}^3$
• B. 1s${}^2$2s${}^2$2p${}^1$
• C. 1s${}^2$2s${}^2$2p${}^2$
• D. 1s${}^2$2s${}^2$2p${}^6$3s${}^1$

Answer 1

The correct option is D

1s${}^2$2s${}^2$2p${}^6$3s${}^1$

Metals form ionic bond as they have low ionization energies.
