It is a chemical element with symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bond. It is a versatile element that forms the basis for all organisms and many of the things we use.
Carbon has a unique ability to form bonds with other atoms of carbon, giving rise to large molecules. This property is called catenation.
Compounds which are linked by only single bonds between the carbon atoms are called saturated compounds.
Compounds having double or triple bonds between their carbon atoms care called unsaturated compounds.
TYPES OF BOND
A bond in which one or more pairs of electrons are shared by two atoms. Since no charged particle is formed ,so generally covalent bond are poor conductors of electricity.
A bond in which one or more electrons from one atom are removed and attached to another atom, resulting in positive and negative ions which attract each other.
Metallic bonds are formed by the attraction between the metal ions and delocalized or “free” electrons
Allotrope is the property of an element to exist in two or more physical forms.
ALLOTROPES OF CARBON
The element carbon occurs in different forms in nature with widely varying physical properties. Three main allotropes of graphite, diamond, and buckminsterfullerene.
