Chemical Bond: The force by which

different atoms are binded together to

form a molecule is called a chemical bond.

•During chemical combination there is give or take or share of

electrons.

•Due to this there is separation of charge.

•Due to separation of charge the atoms or group of atoms exert

force upon each other.

•Due to this force atoms in a molecule are held together

•This binding force is called a chemical bond.
