Lewis Beverage cup structure in the case of NH3 is shown by the valence electrons surrounding the nitrogen atom.
The dot dot arrangement in the case of NH3 displays that the N atom connects one pair of electrons with each of the three H atoms, resulting in a complete of a trio united 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 structure.
In the dot dotpoint representation of ammonia, the N atom is enveloped by three dots, each representing a pair of connected electrons with a H atom.
