Like carbon, silicon also exhibit catenation.
Reason: Silicon has 4 electrons in its outermost shell. This makes both donating and receiving electrons between elements difficult due to high ionisation enthalpies and electron gain enthalpies required to remove or accept electrons. Hence, it develops a tendency to share electron, thus forming covalent bonds. The most stable bond it forms is with atoms of the same element. This results in high catenation property.
