Валентность Серы (S) равна -2, +2, +4, +6

Answer 2

Valency, also known as valence or oxidation state, is a measure of an element's ability to combine with other elements. Here are the valencies of silicon, chlorine, and sulfur:

1. Valency of Silicon (Si): Silicon is an element from Group 14 of the periodic table. It has four valence electrons, so its valency is 4.

2. Valency of Chlorine (Cl): Chlorine is an element from Group 17 of the periodic table. It has seven valence electrons, so its valency is 1 (in the case of negative ions like chloride) or 7 (in the case of positive ions).

3. Valency of Sulfur (S): Sulfur is an element from Group 16 of the periodic table. It has six valence electrons, so its valency is 2 (in the case of negative ions like sulfide) or 6 (in the case of positive ions).

It's important to note that elements can have multiple valencies depending on the type of chemical compounds they form. The valencies mentioned above are the most common valencies for these elements.
