Most hardest element in the universe?

Answer 1

Hardness, as measured on the Mohs scale, *is* related to the element in question but a large part of what causes a substance to be "hard" or not is dependent on how the atoms are bound together and the circumstances of the environment. The hardest naturally occurring substance on earth is diamond, which is composed of Carbon on the Periodic Table. Some man-made ceramics are harder, but these are composite materials with more than one element.

Answer 2

Carbon, when in its crystalline form (known familiarly as diamond), is the hardest element known to man. Carbon also exists in other natural forms or allotropes, such as graphite - which is very soft, as well as in synthetic multi-atomic configurations such as the fullerenes - which include Buckyballs and nanotubes.

Answer 3

Osmium is the hardest element in the periodic table. Osmium is a chemical element that has the symbol Os and atomic number 76. Osmium is a hard, brittle, blue-gray or blue-black transition metal in the platinum family, and is the hardest, densest natural element. It has a Brinell hardness of 3920 MPa.

Contrary to what the last poster thought, transition metals are still true metals. They were confusing the term with "metalloid" which means it is in between metals and non metals.

Answer 4

The hardest element is diamond, which is made from 100% carbon.

Answer 5

Carbon, when in the allotropic form of diamond.

Answer 6

The element that makes the strongest material is carbon, and the material which is made is graphene.

Answer 7

The hardest element is carbon when it is in the form of the diamond. However, it is not found as frequently as some other elements.

Answer 8

carbon in the form of diamond
