Chapter 13, Problem 4E

Interpretation Introduction

Interpretation:

Lewis diagrams for the molecules ${\text{NH}}_{\text{4}}^{\text{+}}{\text{, PH}}_{\text{3}}{\text{, NHF}}_2$ are to be drawn.

Concept introduction:

Lewis diagram is the electron dot model of the diagram showing the each pair of electrons between the two atoms leading to formation of one covalent bond.

Lewis diagrams follow the octet rule when drawn, that is, the total number of electrons around each can be maximum eight.
