Answer 1

Answer:

phosphorus -3.5

chlorine-1

silicon -4

argon -0

Answer 2

An element's valence, also known as Valency, is a measure of its ability to combine with other atoms to create chemical compounds or molecules.

Explanation:

The valency of:

1. Phosphorus: Phosphorus has an atomic number of 15. It has a 2,8,5 electrical arrangement. As a result, it requires three electrons to complete its outermost shell and achieve stability. As a result, its valency is 3.
2. Chlorine: Because it has seven valence electrons, chlorine belongs to group 17. It has a valency of one.
3. Silicon: Silicon's valence shell has four outermost electrons, which is less than eight. As a result, silicon atoms have a valency of four.
4. Argon: The valency of Argon is eighteen.
