👉 Why is diamond the hardest natural substance on earth?

Diamond will always be a girl’s best friend, but it may soon lose favour with industrial drillers. The gemstone lost its title of the “world’s hardest material” to man-made nanomaterials some time...

👉 Why is diamond the hardest substance?

The reason diamond is so hard has to do with the arrangements of carbon atoms in its crystalline form, which has a very high packing factor. Bedrock can be made from many different substances, with a hardness anywhere from 1 to 9. So even the hardest bedrock is still not as hard as diamond. What is the hardest word in the world?

👉 Are diamonds the hardest substance on earth?

While diamonds are classically viewed as the hardest material found on Earth, they are neither the strongest material overall nor even the strongest naturally occurring material… Diamonds are still one of the hardest naturally occurring and abundant materials on Earth, but these six materials all have it beat.

Why is diamond known to be the hardest substance?

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.
