Carbon And its Compounds
Carbon is a typical non-metal present in earth's crust to the extent of 0,02% by mass.
All living organisms contain carbon and hydrogen as their essential compounds.
The compounds of carbon are covalent in nature formed by the electron sharing in the bonding atoms.
Organic compounds are the hydrocarbons and their derivatives.
Allotropes of carbon
The three allotropes of carbon are:
Diamond
Graphite
Fullerene
Among these diamond is the hardest substance known
Graphite is a good conductor of heat and electricity
Uses of graphite
Graphite is used to make electrodes of electrolytic cells.
Being soft and greasy it is used to lubricate the parts of machines
It is also used as a moderator in nuclear power plants
Mixed with wax and clay, graphite is used for making cores of lead pencils as it can mark the paper black.
