Question

Why Diamond is called a Hard Substance ?​

Answer 1

Answer:

The minerals that create a diamond along with their shape make them the strongest gemstone. Diamonds are made from carbon that has been under extreme pressure and heat found in depths of 87 to 120 miles of the Earth’s mantle, where they are created in during a 1-3.3 billion-year time frame. The heat and pressure causes the diamonds molecules to change so that they’re so close together, the molecules can’t move (known as covalent bonding). The closeness of these molecules forms a rigid bond, therefore making the diamond hard.
