Question

in the water molecule (h2o) how many of its own electrons does the oxygen atom share with each hydrogen? (a) single bonds (b) double bonds (c) triple bonds

Explanation:

Step1: Recall covalent - bond concept

In a covalent bond, atoms share electrons. In a water molecule ($H_2O$), oxygen forms covalent bonds with hydrogen.

Step2: Analyze bond type in water

Oxygen has 6 valence electrons and hydrogen has 1 valence electron. Oxygen needs 2 more electrons to complete its octet and hydrogen needs 1 more electron to complete its duet. Oxygen forms single covalent bonds with each hydrogen. In a single covalent bond, 1 electron from each atom is shared. So oxygen shares 1 of its own electrons with each hydrogen.
