Electron pair dot structure in the case of NH3 is portrayed
by the valence electrons surrounding the nitrogen atom.
The dot dot structure in the case of NH3 reveals that the N atom joins 1 pair of e- with each of the three hydrogen atoms, resulting in a complete of three connected pairs of electrons.
The NH3 molecule adopts a trigonal pyramidal structure due to the placement of the outer electrons according to its Electron pair Beverage cup arrangement.
In the dot dotpoint representation of ammonia, the N atom is enclosed by three spots, each representing a pair of connected electrons with a H atom.
