Electron pair dot structure for NH3 is illustrated by the outer electrons surrounding the N atom.
The dot dot structure in the case of NH3 displays that the N atom joins one pair of electrons with each of the three H atoms, resulting in a total of 3 shared pairs of electrons.
The NH3 molecule takes a three-sided pyramid-like shape because of the arrangement of the valence electrons according to its Electron pair Beverage cup structure.
In the dot symbol representation of ammonia, the nitrogen atom is encircled by three spots, each representing a pair of united electrons with a H atom.
