Electron pair dot arrangement for NH3 is portrayed by the outer electrons surrounding the N atom.
The Lewis point structure for ammonia reveals that the N atom unites 1 pair of e- with each of the three hydrogen atoms, resulting in a total of a trio shared pairs of electrons.
The ammonia molecule takes a trigonal pyramidal structure attributed to the arrangement of the outer electrons according to its Lewis Beverage cup arrangement.
In the dot dotpoint representation of NH3, the N atom is enclosed by three points, each representing a pair of connected electrons with a hydrogen atom.
