Crystal Structures

Solids are present all around us. They have different properties and applications. Diamond and graphite are two well-known solids. Diamond is the hardest material in the world and is used in making jewelry. Graphite on the other hand is soft. The lead of your pencil is graphite. Why are they so different in appearance and properties despite the fact they are chemically the same? Both are allotropes of carbon. The answer lies in the structure, the way constituent particles are arranged in the solids.

Question

Alloying can harden the metals because
the foreign atoms are stronger and harder
the foreign atoms produce stronger attractive forces between the metal atoms
the foreign atoms increase the energy of the metal atoms
