Valency of Elements in Compounds

In chemical compounds, the valency of an element is a measure of its combining power with other atoms when it forms chemical compounds. Let's explore the valency of the elements in the given compounds.

ZnS (Zinc Sulfide): - The valency of Zinc (Zn) is typically +2, and the valency of Sulfur (S) is -2.

CuS2 (Copper (II) Sulfide): - The valency of Copper (Cu) in this compound is +2, and the valency of Sulfur (S) is -2.

Al2S3 (Aluminum Sulfide): - In Aluminum Sulfide, the valency of Aluminum (Al) is +3, and the valency of Sulfur (S) is -2.

SnS2 (Tin (II) Sulfide): - The valency of Tin (Sn) in this compound is +2, and the valency of Sulfur (S) is -2.

P2Sn (Tin (IV) Phosphide): - The valency of Phosphorus (P) is typically -3, and the valency of Tin (Sn) in this compound is +4.

In summary: - Zinc (Zn) has a valency of +2 in ZnS. - Copper (Cu) has a valency of +2 in CuS2. - Aluminum (Al) has a valency of +3 in Al2S3. - Tin (Sn) has a valency of +2 in SnS2 and +4 in P2Sn.

I hope this helps! If you have any more questions or need further clarification, feel free to ask.
