Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why is carbon such an important atom?
A
it’s atom number 6 on the periodic table
B
it’s found in organic compounds
C
it must easily forms hydrogen bonds with water in our bodies, which helps water become more soluble
D
it readily forms bonds with itself and other atoms because of its desire to get 4 more valence electrons
Explanation: 

Detailed explanation-1: -To achieve stability, carbon must find four more electrons to fill its outer shell, giving a total of eight and satisfying the octet rule. Carbon atoms may thus form bonds to as many as four other atoms.

Detailed explanation-2: -Carbon has the ability to form covalent bonds with other atoms of carbon giving rise to a large number of molecules through self linking property. This property is called catenation.

Detailed explanation-3: -Carbon is phenomenally important to life as we understand it. The ability to form bonds with up to four different atoms gives carbon an incredible chemical diversity, and allows for carbon to make long chains and aromatic compounds.
