Why carbon shows catenation but silicon does not?

Explanation:
Why isn't silicon capable of the same extent of catenation as carbon? The silicon atom is larger than the carbon atom, its covalent radius is 111 pm carbon is 77 pm which makes it more difficult for silicon to form a tetrahedral arrangement with other atoms. The Si-Si bond is also longer and weaker than the C-C bond.
