Electron pair Beverage cup arrangement in the case of NH3 is illustrated by the outer electrons surrounding the N atom.
The dot dot arrangement for NH3 reveals that the N atom unites 1 pair of e- with each of the three hydrogen atoms, resulting in a complete
of three joined pairs of electrons.
The NH3 molecule takes a trigonal pyramidal shape attributed to the placement of the outer electrons according to its Electron pair dot structure.
In the Lewis dotpoint depiction of NH3, the N atom is surrounded by three points, each representing a pair of connected electrons with a H atom.
