Electron pair dot arrangement in the case of NH3 is portrayed by the outer electrons surrounding the
N atom.
The Lewis dot arrangement for NH3 reveals that the N atom joins 1 pair of electrons with each of the three hydrogen atoms, resulting in
a total of three joined pairs of electrons.
The NH3 molecule takes a three-sided pyramid-like form due to the placement of the outer electrons according to its Electron pair dot arrangement.
In the dot symbol depiction of NH3, the N atom is surrounded by three dots, each representing a pair of united electrons with a H atom.
