Lewis dot arrangement for NH3 is shown by the valence electrons surrounding the N atom. The dot dot structure in the case of ammonia reveals that the nitrogen atom connects 1 pair of e- with each of the three H atoms, resulting in a complete of 3 connected pairs of electrons. The ammonia molecule adopts a trigonal pyramidal shape attributed to the distribution of the outer electrons according to its Lewis Beverage cup arrangement. In the dot dotpoint representation of ammonia, the nitrogen atom is encircled by three spots, each representing a pair of shared electrons with a H atom.
