Chapter 4.1, Problem 1QQ

Interpretation Introduction

Interpretation:

Identification of the correct concept of electron transfer has to be chosen from the given options.

Concept Introduction:

Chemical bond:

It is the force that acts between two or more atoms to hold them together in a molecule or ion.

A chemical bond is an attraction between atoms brought about by –

• A sharing of electrons between two atoms or ions
• A complete transfer of electrons.

Ionic bonds:

The ionic or electrovalent bond is the chemical bond formed between two atoms by the transfer of one or more valence electrons from one atom to other.

Factors affecting the formation of ionic bonds:

• The ionization energy decreases, increase in ease of formation of a cation.
• The Electron affinity increases, the easier will be the formation of anion.
• Increase the lattice energy, increase the lattice energy.
