Answers (2)

Ionic bond: The bond which is formed by the transferring electrons from one atom to other atom completely, and as a result positive and negative ions are formed in this bond. Here, the ions are held together through electrostatic force of attraction. e.g.,

The formation of calcium fluoride,

Ca\rightarrow Ca^{2+}+2e^{-}

[Ar]4s^{2}[Ar]

F+e^{-}\rightarrow F^{-}

[He]2s^{2}2p^{5}[He]2s^{2}2p^{6}\; or[Ne]

Ca^{2+}+2F^{-}\rightarrow CaF_{2}\; or\; Ca^{2+}(F^{-})_{2}

The information of NaCl

Na\rightarrow Na^{+}+e^{-}

[Ne]3s^{2}3p^{5}[Ne]3s^{2}3p^{6}\; or[Ar]

Na^{+}+Cl^{-}\rightarrow NaCl\; or\; Na^{+}Cl^{-}

Covalent bond: The bond which is formed between the two atoms of non-metals by mutual sharing of electron between them is called covalent bond, e.g., the formation of chlorine molecule can be explained as 

Also formation of HCl:
