Why carbon exhibits catenation character more than other elements of group 14?

Explanation

Carbon has maximum tendency to catenate due to its small size for which C - C bond is very strong and this results in the formation of long chain of convalent bonds like open , branched and ring chain of C - atoms etc.

However down the group increasing atomic size and decreasing bond strengths the tendency to exhibit catenation decreases among other members of the group.
