Draw the Lewis structure for the ammonia molecule. Be sure to include all resonance structures that satisfy the octet rule.

Answer:

Attached Lewis structure

Explanation:

To draw the Lewis structure, we need to consider the octet rule: atoms will gain lose or share electrons to complete their valence shell with 8 electrons. Hydrogen is an exception because it is completed with 2 electrons (duet). N and H are nonmetals so they form covalent bonds, that is, they share electrons.

  • N has 5 valence electrons, so it has to share 3 pairs of electrons.
  • Each H has 1 valence electron, so it has to share 1 pair of electrons.

The Lewis structure is attached and there are no resonance structures since there are no pi electrons.
