Solution: The answer is (b) Metalloid

Explanation: Silicon has an electrical configuration of 2, 8, and 4 atoms. Considering that the outermost shell has just four electrons, it requires an additional four electrons in order to achieve the inert gas configuration. As a result, in order to complete its octet, silicon forms a covalent bond with another element. Covalent bonds are created when electrons are shared between two or more atoms. Silicon atoms establish covalent bonds with their neighbor’s atoms by sharing their valence electrons with them.
