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.
