Explain the formation of the chemical bonds.

Solution

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 CH4.
  2. It is the simplest alkane and it consists of four hydrogen atoms and one carbon atom.
  3. In a CH4 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(NaCl) is a very common example of this.

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