Answer:

Properties Of Carbon :

Explanation:

Carbon:

Symbol: C

Electronic Configuration: 2 , 4

Valency : 4 (Tetra-valency)

Occurrence in nature →Earth's crust → 0.02% in the form of minerals like carbonates, coal, petroleum.

In atmosphere -0.03% in carbon dioxide is ( gaseous form)

Properties of carbon:

Carbon forms Covalent is bonding and Covalent compounds wwhich do not conduct electricity.
Carbon has three allotropes i.e Diamond, Graphite and Fullerenes.
In diamond carbon atoms bonded together in tetrahedral lattice arrangement.
In graphite carbon atoms are bonded together in sheets of hexagonal lattice.
In Fullerenes ccarbon atoms are bonded together in spherical, tubular, or ellipsoidal forms.
Carbon plays a major role in organic compounds.
Carbon is a Tetravalency. (valency :4)
So that it is easily share the electrons so that it gives a possibility of large number of compounds. Carbon compounds are also called as organic compounds. Carbon compounds are also called organic compounds.
