Chapter 12, Problem 3A

Interpretation Introduction

Interpretation:

The various types of chemical bond are to be described.

Concept introduction:

Whenever two or more atoms combine to form molecule, these atoms are joined together using a bond called chemical bond.

Answer to Problem 3A

Chemical bond is an attraction between atoms which helps to make a chemical compound. Electrons are most important for making the bonds.

Ionic bond formation requires complete transference of electrons.

Covalent bond involves sharing of electrons between the atoms.

Explanation of Solution

Chemical bond is generally of two types:

• Ionic bond
• Covalent bond

Ionic bonds are formed when there is complete transfer of electrons from one atom to another forming the bonds.

Covalent bond is formed by sharing of electrons between the atoms forming the bonds

In all types of bond formation, electrons play an important role.

Conclusion

Thus, chemical bond helps to join atoms to make a compound either by sharing or complete transference of electrons.
