Electron pair Beverage cup structure for ammonia is a representation of the valence electrons surrounding the nitrogen atom. The dot point structure for NH3 exhibits that the N atom connects a solitary pair of electrons with each of the three hydrogen atoms, resulting in a complete of three joined pairs of electrons. The ammonia molecule adopts a trigonal pyramidal structure due to the distribution of the valence electrons according to its Lewis dot arrangement. In the dot dotpoint depiction of NH3, the nitrogen atom is enclosed by three spots, each representing a pair of connected electrons with a hydrogen atom.
