Question

What is the valency of sulfur?

Answer 1

Valence, also known as valency or valency number, is a measure of the number of chemical bonds formed by the atoms of a given element. The concept was developed in the middle of the nineteenth century in an attempt to rationalize the formulae of different chemical compounds. Although it has fallen out of use in higher level work with the advances in the theory of chemical bonding, it is still widely used in elementary studies where it provides a heuristic introduction to the subject. Thus, sulfur has six valence.
