Carbon & its
Allotropes:
Allotropes: Allotropes are different physical forms of the same
element. For example, Carbon exists in 2 allotropes of Graphite and Diamond.
Graphite is black and greasy, while diamond is the hardest material known to
mankind.
Diamond:
Carbon in diamond forms a tetrahedral structure in which each
carbon is bonded with 4 other carbon atom with strong and rigid covalent bonds.
These account for the very high melting point of diamond and also makes it the
strongest substance known to mankind. Since, all the valence electrons are
bonded, and no free electrons are present, diamond cannot conduct electricity.
