Ionic &Covalent bond
❖ IONIC OR ELECTROVALENT BOND
• Ionic bond is formed when one atom transfers one or more
electrons from its outer shell to complete the octet.
• The atom which loses electrons becomes positively charged.
• The atom which gains electrons completes its octet and becomes
negatively charged.
• The charged particles formed by the loss and gain of electrons
from the neutral atoms are called positive Ion and negative ion
us
respectively. Pl
• The positive and negative ions are attracted to one another by
considerable electrostatic force which constitutes the ionic

(electrovalent) bond.

• Thus, ionic bond is defined as the electrostatic force of attraction

• The necessary condition for the formation of this bond is that one

of the atom(s) should have a tendency to lose electrons and other

should be capable of accepting the electrons
• ie., one element should be electropositive (metal) and the other
electronegative (non - metal).

• The electronic configuration of sodium atom is 2,8,1.
• By losing one electron of its outermost shell it acquires the inert

• The electronic configuration of chlorine is 2,8,7.
• By accepting the electron released by sodium, chlorine attains
inert gas configuration of argon and changes into ion.
