Chapter 9, Problem 9.69QP

Interpretation Introduction

Interpretation:

The Lewis structure for ${\text{SeF}}_{\text{4}}\text{and}{\text{SeF}}_{\text{6}}$ has to be drawn and the octet rule for $\text{Se}$ has to be checked.

Concept Introduction:

Octet Rule:

The octet rule states that the noble gas electron configuration is attained by the element, when the element either loses or gains or shares its atoms. The formulas for the compounds that contain specific elements can be predicted with the help of Octet rule. The octet rule holds good for those compounds that are made of elements present in second period and hence the important study on organic compounds that mainly consists of Carbon, Nitrogen and Oxygen atoms can be done with the help of Octet rule. The loss gain or sharing electrons of particular atom is dependent on properties of atoms that are determined by the number of subatomic particles inside in the atom.

Lewis structure:

The Lewis structure otherwise known as Lewis dot diagrams or electron dot structures that show the bond between atoms and lone pairs of electrons that are present in the molecule. Lewis structure represents each atom and their position in structure using the chemical symbol. Excess electrons forms the lone pair are given by pair of dots, and are located next to the atom.
