Detailed explanation-1: -In a silicon atom, the outermost orbital contains 4 electrons, therefore its valency is 4.

Detailed explanation-2: -Silicon atom has 4 electrons in its outermost shell. Hence, valency of silicon atom is 4.

Detailed explanation-3: -So basically, silicon is an atom that has an atomic number of 14 which actually means that silicon carries two electrons in the first shell, eight in the send shell, and four electrons are present in the third shell. Therefore, silicon consists of four valence electrons in it.

Detailed explanation-4: -In its first shell, it has two electrons, in the second shell, eight electrons, and in the third shell, four. Since the electrons are the outermost electrons in the third shell, silicone has four valence electrons. Hence, the number of valence electrons in silicon is four.

Detailed explanation-5: -What is Tetravalency? Carbon has a valency of four, so it is capable of bonding with four other atoms of carbon or atoms of some other monovalent element. This is known as tetravalency of carbon.
