Question

Silicon:
Valency and Electronic configuration​

Answer 1

Answer:

The number of valence electrons that are present in an atom can be determined from that atom's electron configuration. Valence electrons are found in the orbitals associated with an atom's highest occupied energy level

Explanation:

Valency is calculated by using number of valence electrons present in an atom. The number of electrons present in the last shell of an atom and take part in chemical bond formation are known as valence electrons. ... So, electronic configuration expresses the valence electrons which are related to the valency of an atom.

hope this is your answers

Answer 2

Valency of silicon

Atomic number of silicon is 14. The electronic configuration of the element is – K=2, L=8,m=4. According to the electronic configuration the valency is +4 or -4 because silicon can either gain 4 electrons or lose 4 electrons because it is a noble gas. Hence, valency of silicon is 4.
