Question

The oxidation number and covalency of sulphur in sulphur molecules (S_g) are:

Options

• 0 and 2

• + 6 and 8

• 0 and 8

• + 6 and 2

Answer 1

0 and 2

Explanation:

An element's oxidation number is zero. As a result, it has a covalency of 2, since S in S_g has no oxidation number. Each sulphur atom in the S_g molecule is further bonded to two other sulphur atoms, resulting in a covalency of two.
