What is electronegativity, and how does it relate to nonpolar covalent bonds and polar covalent bonds?

Expert Solution
Summary Introduction

To review:

The concept of electronegativity and its relation to polar and nonpolar covalent 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. 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 or sharing the electrons.

Explanation of Solution

A bond formed by the electron transfer between atoms of two different elements is called the ionic bond as ions are formed in it. Whereas the bond formed via the sharing of electrons is called the covalent bond. Other types of bonds are hydrogen bonds and Van der Waals forces. These are weaker in comparison to ionic and covalent bonds and do not involve sharing or transfer of electrons.

A covalent bond is formed by the sharing of electrons between two atoms. These atoms may be of the same or different elements. These atoms can neither donate nor lose electrons. Such atoms have four or more electrons in their valence shell...
