Question

2. Carbon has four electrons in its valence shell. How does carbon attain
stable electronic configuration?
​

Answer 1

$\huge \mathfrak \color{pink}{Answer}$

The configuration of Carbon = 6

k shell have = 2 electron

L shell have = 4 electron

Now:-

Carbon has four electrons in the outermost shell. It needs to gain , lose or share electrons in order to achieve stable configuration.

Therefore, carbon shares electrons with other atoms of carbon or with atoms of other elements.

They form Covalent bond.

I have given example of CO2 and CCl2 formation.

Answer 2

Yes, Carbon has 4 electrons in its valence shell. The thing carbon can do is:-

• It can gain four electrons forming $\tt \: {c}^{4 - }$ anion. But it would be difficult for nucleus to hold for extra electrons.

• It can loose four electrons forming $\tt \: {c}^{4 + }$ cation. But it would require a lot of energy to remove four electrons for just holding two electrons.

Carbon overcomes this problem by sharing its valence electrons with other atoms of carbon or with atoms of other elements. Carbon has the unique ability to form bonds with other atoms of carbon giving rise to large molecules and this property is called as catenation.
