Chapter 9.2, Problem 1PE

Interpretation Introduction

Interpretation:

Using the Lewis dot structure, the formation of Barium hydride has to be represented.

Concept Introduction:

Lewis dot structure: In the Lewis dot structure, an element will be represented by its elemental symbol. It will be surrounded by dots. Each dot represents the valence electron of that element. So the Lewis dot structure enables to represent an element with its valence electrons in chemical bonding.

Steps for drawing the Lewis dot structure:

Step 1: Write the electronic configuration of the element.

Step 2: Find the number of valence electrons that are present in its valence shell.

Step 3: Represent that number of valence electrons in dots, around the elemental symbol.

Step 4: If a covalent bonding is supposed to exist between two elements then that should be represented as a solid line in between those two elements.
