Chapter 2.3, Problem 1SB

Summary Introduction

To review:

The formation of ionic bonds.

Introduction:

The electrons present in the outermost shell in an atom are called valence electrons and the shell is called the valence shell. These electrons determine the chemical activity of an atom or element. The valence shell is different for different elements and depends on the number of electrons present in its atom. An atom with a complete valence shell is chemically stable. In order to complete their valence shells, atoms combine together to form chemical bonds by transferring the electrons or by sharing them.
