Lewis dot arrangement for NH3 is shown by the valence electrons surrounding the nitrogen atom.
The dot point structure in
the case of ammonia unveils that the nitrogen atom shares one pair of e- with each of the three H atoms, resulting in a overall of a trio united pairs of electrons.
The NH3 molecule adopts a trigonal pyramidal shape due to the distribution of the valence electrons according to its Electron pair dot arrangement.
In the dot symbol depiction of NH3, the nitrogen atom is surrounded by three dots, each representing a pair of united electrons with a hydrogen atom.
