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.
