Electron pair dot arrangement in the case of NH3 is portrayed by the outer electrons surrounding the N atom.
The dot dot arrangement for NH3 displays that the nitrogen atom joins one pair of e- with each of the three hydrogen atoms, resulting in a total of three joined pairs of electrons.
The NH3 molecule takes a trigonal pyramidal form attributed to the placement of the valence electrons according to its Lewis Beverage cup structure.
In the dot symbol representation of ammonia, the N atom is surrounded by three spots, each representing a pair of joined
electrons with a H atom.
