Why is Carbon called Tetravalent?
- The word 'Tetra' means 4
- The word 'Valent' means Valency
- The electronic configuration of C is 2,4.
- 4 electrons are present in the outermost shell.
- Therefore, it can either lose 4 electrons or gain 4 electrons.
- Hence 4 is the Valency .
- That's why we call it tetravalent.
Since Carbon has valency of 4, it is called Tetravalent
