Chapter 4, Problem 4RQ

Interpretation Introduction

Interpretation:

The number of electrons in a duet and in an octet should be determined.

Concept Introduction:

• Octet rule: According to this rule, all atoms can lose, gain or share their valence electrons in order to complete their octet or get 8 valence electrons; the electron configuration of the nearest noble element.

• Valence electron: The electrons which are present in the outer most energy level are known as valance electron. This can be calculated by the group number of the element. Generally, the group number is same as the valance electrons of any elements.
