Question

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

Answer 1

In ammonia molecule(
`NH_(3)` ), three hydrogen atoms form covalent bonds with nitrogen atom.

Step-by-step explanation:

• A covalent bond is an intramolecular interaction. It is formed by sharing of electron pairs between atoms to gain stability.

• In
  `NH_(3)` 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
  `NH_(3)`.
