Lewis Beverage cup arrangement for NH3 is depicted by the valence electrons surrounding the N atom. The dot dot arrangement for ammonia displays that the nitrogen atom connects 1 pair of e- with each of the three hydrogen atoms, resulting in a total of 3 joined pairs of electrons. The NH3 molecule takes a trigonal pyramidal shape attributed to the placement of the valence electrons according to its Lewis Beverage cup structure. In the dot symbol depiction of ammonia, the nitrogen atom is enclosed by three dots, each representing a pair of joined electrons with a H atom.
