Question

Why is diamond so hard?explain in terms of its structure.

Answer 1

Answer:

diamond is so hard because it's molecules are tightly packet and no intramolecular space is there

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.
