Chapter 6, Problem 6.85QP

Interpretation Introduction

Interpretation: The group of elements which violates the octet rule should be briefly explained.

Concept Introduction:

• According to octet rule an atom is said to be stable if its valence shell has 8 electrons and it can be achieved by gaining, losing or sharing of electrons with other atoms.
• If the valence shell of atom contains 8 electrons, it gets the electronic configuration of noble gas where the outer shell electronic configuration is ${\text{ns}}^{\text{2}}{\text{np}}^{\text{6}}$
• Since the valence shell of noble gases is already filled and has 8 valence electrons, it violates octet rule.
