Lewis dot structure in the case of ammonia is illustrated by the valence electrons surrounding the N atom.
The Lewis point structure for ammonia reveals that the nitrogen atom shares one pair of e- with each of the three H atoms, resulting in a overall of
three united pairs of electrons.
The ammonia
molecule takes a trigonal pyramidal shape because of the distribution of the valence electrons according to its Electron pair dot structure.
In the dot symbol depiction of ammonia, the N atom is encircled by three points, each representing a pair of joined electrons with a H atom.
