Electron pair dot arrangement for ammonia is depicted by the outer electrons surrounding the nitrogen atom. The dot point structure for NH3 unveils that the N atom unites one pair of e- with each of the three hydrogen atoms, resulting in a total of 3 shared pairs of electrons. The ammonia molecule adopts a trigonal pyramidal form due to the arrangement of the outer electrons according to its Electron pair Beverage cup structure. In the Lewis symbol representation of ammonia, the N atom is enveloped by three dots, each representing a pair of united electrons with a hydrogen atom.
