Determine the total number of electrons in the bonds between the nitrogen atom and the three hydrogen atoms in the ammonia molecule, NH3.

In ammonia molecule( ), three hydrogen atoms form covalent bonds with nitrogen atom.

Explanation:      

A covalent bond is an intramolecular interaction. It is formed by sharing of electron pairs between atoms to gain stability. In the molecule, three covalent bonds are present. A hydrogen atom has 1 valence electron. The nitrogen atom has 5 valence electrons. Thus it needs 3 more electrons to achieve stability.  So, now these atoms will share their electrons. Each hydrogen atom will share its electron with a nitrogen atom. Thus the octet of nitrogen is complete now. And the hydrogen atom has become stable. Thus 3 covalent bonds have been formed between these atoms forming a stable molecule of .
