Group 14 elements are carbon, silicon, germanium, tin and lead. These group 14 elements have a special tendency of catenation (tendency to form long chains with atoms of itself) which decreases as we move down the group. The order of catenation property is: C >> Si > Ge >> Sn > Pb.
Catenation is the linkage of atoms of the same element into longer chains. Catenation most readily occurs in carbon which forms covalent bonds with other carbon atoms to form longer chains and structure.C with the least diffuse p orbital can form a longer p-p sigma bond. This sigma overlap is strong enough to form stable C-C long chains.
