Question

Carbon shows the catenation property but Lead does not. Why?

Answer 1

Lead reacts quite fastly during covalent bonding.Hence,it does not show catenation.

Answer 2

carbon shows unique nature I.e catenation means self linking with another carbon atom...

Only carbon shows this property due to its very small size. .

Due to small size force of attraction between electrons and protons are very high so bond formed between carbon - carbon is very strong as compared to any atom....

This is reason why only carbon shows property of catenation...
