Question

Why diamond is hard and give its structure

Answer 1

Diamond has planer tetragonal structure and every carbon atom is bonded to four neighbouring atom. Diamond has three dimensional structure which makes it very hard

Answer 2

• Diamond made up of carbon atoms.
• The outermost shell of each carbon atom has four electrons.
• In diamond, these electrons are shared with four other carbon atoms to form very strong chemical bonds resulting in an extremely rigid tetrahedral crystal.
• It is this simple, tightly-bonded arrangement that makes diamond one of the hardest substances on Earth.
