Electron pair dot structure in the case of ammonia is shown by the valence electrons surrounding the nitrogen atom.
The Lewis dot structure in the case of ammonia exhibits that the N atom unites 1 pair of e- with each of the three H atoms, resulting in a overall of 3 connected pairs of electrons.
The NH3 molecule adopts a trigonal pyramidal shape attributed to the distribution of the outer electrons according to its Electron pair Beverage cup structure.
In the Lewis symbol representation of ammonia, the nitrogen atom is surrounded by three dots, each representing a pair of connected electrons with a hydrogen atom.
