Electron pair dot arrangement for NH3 is shown by the outer electrons surrounding the N atom.
The dot point structure in the case of ammonia reveals that the N atom unites 1 pair of electrons with each of the three hydrogen atoms, resulting in a total of three shared pairs of electrons.
The ammonia molecule takes a three-sided pyramid-like shape because of the distribution of
the outer electrons according to its Electron pair dot structure.
In the Lewis dotpoint depiction of NH3, the nitrogen atom is enclosed by three points, each representing a pair of connected electrons with a H atom.
