Lewis Beverage cup arrangement for NH3 is shown by the outer electrons surrounding the N atom.
The dot dot arrangement in the case of ammonia unveils that the nitrogen atom shares one pair of electrons with each of the three H atoms, resulting in a complete of three joined pairs of electrons.
The NH3 molecule adopts a three-sided pyramid-like shape because of the arrangement of the valence electrons according to its Electron pair Beverage cup arrangement.
In the dot symbol representation of ammonia,
the nitrogen atom is enclosed by three spots, each representing a pair of shared electrons with a H atom.
