Question

what is covalent bond and ionic bond? Explain by taking an example.​

Answer 1

Covalent bond:

• The species which are involved in bonding are only atoms.
• The atoms share their electrons with other electrons.
• These are comparatively weaker and can be polar or non-polar.
• Only non-metals or metalloids are involved in bonding with non-metals.
• Examples are chlorine gas and water.

Ionic bond:

• The species which are involved in bonding are ions.
• The atoms gain or donate their electrons to become stable and form a bond.
• These are comparatively stronger than covalent bonds.
• Only metals are involved in bonding with non-metals.
• Examples are sodium chloride and magnesium oxide.
