Solution

## Formation of chemical bonds:-Chemical bond is the attractive force that holds together the constituent particles in a certain compound.Atoms have a tendency to either share, gain or lose electrons in order to attain a stable electronic configuration.Due to this, a chemical bond is formed and a state of minimum energy is obtained, which results in maximum stability. 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:-Methane is the simplest of saturated hydrocarbons with the chemical formula ${\mathrm{CH}}_{4}$. It is the simplest alkane and it consists of four hydrogen atoms and one carbon atom.In a ${\mathrm{CH}}_{4}$ molecule, sharing of electrons between carbon and hydrogen atoms occurs. These types of bonds are called as covalent bonds. Generally, non-metals form a chemical bond by sharing electrons with each other. An ionic bond is formed as a result of the transference of electrons from one atom to another.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.
