Electron pair Beverage cup structure for NH3 is portrayed by the outer electrons surrounding the N atom. The dot dot structure in the case of ammonia displays that the nitrogen atom connects a solitary pair of e- with each of the three H atoms, resulting in a overall of a trio united pairs of electrons. The ammonia molecule adopts a trigonal pyramidal shape due to the distribution of the valence electrons according to its Lewis Beverage cup structure. In the dot dotpoint depiction of NH3, the N atom is surrounded by three points, each representing a pair of connected electrons with a hydrogen atom.
