Lewis dot structure in the case of ammonia is a representation of the outer electrons surrounding the N atom.
The dot dot structure for NH3 unveils that the N atom shares one pair of e- with each of the three H atoms, resulting in a overall of a trio joined pairs of electrons.
The ammonia molecule takes a trigonal pyramidal structure because of the placement of the outer electrons according to its Lewis dot structure.
In the dot symbol depiction of ammonia, the N atom is enveloped by three dots, each representing a pair of connected electrons with a H atom.
