Question

How does a covalent bond form?

Answer 1

By sharing electrons between two or more non-metallic atoms, covalent bond is formed.

Answer 2

Answer:

• A ‘covalent bond’ is formed in between two non metal atoms to share their electrons.  
• The bond that is formed in between the atoms which share electrons is referred to as covalent bond.
• After involving the bond formation of an each atom attains ‘the electronic configuration’ of a noble gas and gets stability of each atom in a molecule.
• In$\mathrm{H}_{2} \mathrm{O}$ molecule formation two hydrogen atom shares each electron to the oxygen atom. Two covalent bonds are formed in between O-H atoms.

The representation of covalent bond formation in $\mathrm{H}_{2} \mathrm{O}$ molecule is attached below:
