Electron pair Beverage cup structure for NH3 is illustrated by the outer electrons surrounding the nitrogen atom.
The Lewis dot structure for ammonia exhibits 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 shape due to the placement of the valence electrons according to its Lewis dot arrangement.
In the Lewis symbol depiction of ammonia, the N atom is enclosed by three points, each representing a pair of connected electrons with a
hydrogen atom.
