Detailed Solution

 concept - Valency is the number of electrons an atom required to achieve a stable octet configuration. If the last shell contains more than 4, it accepts electrons otherwise it loses electrons for stability.
The valency of a given atom can be determined following the octet rule The octet rule refers to the tendency of atoms to prefer eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react to form more stable compounds. If the number of electrons in the outer shell is between one to four, the valency is the same as the number of valence electrons.
The chemical element silicon, which has the symbol Si and the atomic number 14, may be found in the periodic table. Silicon is a very significant semiconductor due to its atomic structure. Only a small amount of mobility is possible for the silicon atoms since they are locked in place by powerful pressures.
The quantity of valence electrons in an element's atom determines its valency.
Silicon's outermost shell contains 4 electrons. Consequently, silicon atoms have a valency of 4.
Hence, the correct option is (1).
