The reason for the tetravalency of carbon is 'hybridization' between the 2s and 2p subshells of carbon which lead to 4 hybrid subshells 'sp' and thus 4 empty spaces for electrons to be filled
- There are 6 electrons in a carbon atom
- These are arranged into 2,4 into two differnt shells
- These if specified in quantum numbers would be 1s²,2s²2p²
- When carbon comes in proximity with other atom which it can form a bond , it hybridizes its 2s and 2p sub shells to form hybrid shells
- So 4 hybrid sub shells are formed from one 2s subshell and three 2p subshells to form 4 hybrid sp sub shells
- Therefore carbon now has 4 halfilled subshells which can now form covalent bonds with other atoms
- This leads to the tetravalency of carbon

Answer:
It means it has 4 electrons in the outermost shell. - Carbon obeys the octet rule and forms 4 covalent bonds with other atoms to get a stable electronic configuration. Thus, carbon is tetravalent. DP
