Lewis Beverage cup arrangement in the case of ammonia is illustrated by the
outer electrons surrounding the N atom.
The dot dot structure in the case of ammonia displays that the N atom joins one pair of electrons with each of the three H atoms, resulting in a total of 3 connected pairs of electrons.
The ammonia molecule adopts a trigonal pyramidal shape because of the
placement of the valence electrons according to its Electron pair dot structure.
In the Lewis symbol depiction of ammonia, the nitrogen atom is surrounded by three points, each representing a pair of joined electrons with a hydrogen atom.
