Answers

Answered by NayashaSingh

2

Step-by-step explanation:

In the water molecule oxygen combines with two hydrogens and so has a valency of 2. A simple diagram of a water molecule makes this plain. The hydrogen atoms are each sharing one pair of electrons - they have a valency of 1. The oxygen atom is sharing two pairs of electrons - it has a valency of 2.
