Electron pair dot structure for ammonia is a representation of the outer electrons surrounding the N atom.
The Lewis dot structure for NH3 displays that the nitrogen atom connects one pair of e- with each of the three hydrogen atoms, resulting in a overall of 3 united pairs of electrons.
The ammonia molecule adopts a trigonal pyramidal shape because of the placement of the valence electrons according to its Electron pair Beverage cup arrangement.
In the Lewis symbol representation of NH3, the N atom is encircled by three dots, each representing a pair of united electrons with a H atom.
