Electron pair Beverage cup arrangement for NH3 is shown by
the valence electrons surrounding the N atom.
The Lewis dot arrangement for ammonia unveils that the N atom unites 1 pair of e- with each of the three H atoms, resulting in a total of a trio joined pairs of electrons.
The ammonia molecule takes a trigonal pyramidal form attributed to the placement of the outer electrons according to its Lewis Beverage cup arrangement.
In the Lewis dotpoint representation of NH3, the N atom is enveloped by three points, each representing a pair of connected electrons with a H atom.
