Question

Explain the formation of the chemical bonds.

Answer 1

Formation of chemical bonds:-

1. Chemical bond is the attractive force that holds together the constituent particles in a certain compound.
2. Atoms have a tendency to either share, gain or lose electrons in order to attain a stable electronic configuration.
3. Due to this, a chemical bond is formed and a state of minimum energy is obtained, which results in maximum stability.
4. A covalent bond is formed when two atoms share electrons, whereas an ionic bond is formed when atoms lose or gain electrons.

Examples of chemical bonds:-

1. Methane is the simplest of saturated hydrocarbons with the chemical formula ${\mathrm{CH}}_4$.
2. It is the simplest alkane and it consists of four hydrogen atoms and one carbon atom.
3. In a ${\mathrm{CH}}_4$ molecule, sharing of electrons between carbon and hydrogen atoms occurs.
4. These types of bonds are called as covalent bonds. Generally, non-metals form a chemical bond by sharing electrons with each other.
5. An ionic bond is formed as a result of the transference of electrons from one atom to another.
6. Sodium chloride$\left(\mathrm{NaCl}\right)$ is a very common example of this.

Hence, chemical bonds are formed by electron transformation to lower the energy of the system.
