Electron pair dot arrangement for NH3 is a representation of the valence electrons surrounding the N atom.
The dot point structure for NH3 reveals that the N atom shares 1 pair of e- with each of the three hydrogen atoms, resulting in a total of 3 joined pairs of electrons.
The NH3 molecule takes a trigonal pyramidal structure due to the placement
of the outer electrons according to its Lewis Beverage cup structure.
In the dot dotpoint representation of NH3, the N atom is enclosed by three dots, each representing a pair of connected electrons with a H atom.
