• Two lone pairs of electrons

• One lone pair of electrons

Answer 1

In the molecule of water, oxygen atom has two lone pairs of electrons.

Explanation:

A water molecule has 2H atoms and 10 atoms. O has an electrical configuration of 2, 6 and requires 2 electrons to complete its octet.
∴ it shares 2e⁻ with 2H−atoms
