Chapter 6.5, Problem 6.40QAP

Interpretation Introduction

Interpretation:

Octet rule: Atoms have tendency to gain, lose or share electrons so they can have eight electrons in their Outer most shell.

$H,He,Li,Be,$ Has tendency to retain $2$ electrons in the outer most shell, this is known as duplet.

Covalent bond: Covalent bond is formed by sharing to electrons present in valence shell to complete the octet. In the electronic dot structure valence electron is shown by dot.

Concept introduction:

$\left(1\right):$ Write electronic configuration of each participating atom

$\left(2\right):$ Write chemical symbol of each participating atom

$\left(3\right):$ Give one dot for each valence electron

$\left(4\right):$ Do share electron to complete octet or duplet.
