Electron pair dot arrangement in the case of ammonia is portrayed by the outer
electrons surrounding the nitrogen atom.
The Lewis dot structure for NH3 unveils that the N atom shares one pair of e- with each of the three H atoms, resulting in a total of 3 connected pairs of electrons.
The NH3 molecule adopts a
trigonal pyramidal shape because of the arrangement of the valence electrons according to its Electron pair dot arrangement.
In the dot dotpoint representation of ammonia, the nitrogen atom is enclosed by three dots, each representing a pair of united electrons with a H atom.
