Electron pair dot arrangement for ammonia is depicted by the valence electrons surrounding the N atom. The dot point structure for NH3 unveils that the N atom joins 1 pair of e- with each of the three hydrogen atoms, resulting in a total of three united pairs of electrons. The NH3 molecule adopts a trigonal pyramidal structure because of the distribution of the outer electrons according to its Electron pair Beverage cup arrangement. In the dot dotpoint representation of ammonia, the N atom is enclosed by three points, each representing a pair of connected electrons with a hydrogen atom.
