Answer 3

Valencies of Oxygen and Hydrogen

The valencies of oxygen and hydrogen are as follows:

- Oxygen (O) has a valency of 2. - Hydrogen (H) has a valency of 1.

Valency refers to the combining capacity of an element, or the number of electrons an atom of that element can gain, lose, or share when it forms chemical compounds. Oxygen has a valency of 2 because it can gain or share two electrons to achieve a stable electron configuration, while hydrogen has a valency of 1 because it can gain or share only one electron to achieve stability.
