Question

In potassium chloride, Ionic bond formation takes place between potassium and chloride.

• A. True
• B. False

Answer 1

The correct option is A True

In KCl.

K Z=19 $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^1$

Cl Z=17 $1s^{2}2s^{2}2p^{6}3s^{2}3p^5$

Potassium looses one electron to 3p orbital of Cl and attains stability and Cl gains electron to attain stability. hence the K-Cl bond is ionic
