Lewis Beverage cup arrangement for NH3 is depicted by the valence electrons surrounding the nitrogen atom. The dot dot arrangement for ammonia unveils that the nitrogen atom connects 1 pair of electrons with each of the three hydrogen atoms, resulting in a total of three shared pairs of electrons. The NH3 molecule takes a three-sided pyramid-like form attributed to the arrangement of the valence electrons according to its Lewis dot structure. In the dot dotpoint depiction of ammonia, the nitrogen atom is enveloped by three spots, each representing a pair of connected electrons with a hydrogen atom.
