Question

How does an atom of carbn attain noble gas configuration?

Answer 1

Carbon has 4 electrons in its outer most orbits and in order to attain the noble gas configuration it should either lose or gain 4 electrons.

Being a tetra valet its property is to gain or lose 4 electrons to be stable as noble gases.

Answer 2

Carbon has 4 electrons in its outer most orbits and in order to attain the noble gas configuration it should either lose the 4 electrons and gain helium gas configuration or gain 4 electrons to obtain neon gas configuration

But is very difficult for it to gain or lose 4 electrons as very high energy is required to remove 3rd or 4th electrons and also it's very difficult for it to gain 4 electrons and hold it.

Hence carbon atom undergoes covalent bonding with other atoms to become stable
