Lewis Structure for NH3 Ammonia UMD
Electron pair dot arrangement in the case of NH3 is depicted by the outer electrons surrounding the N atom. The dot dot arrangement in the case of NH3 reveals that the N atom joins one pair of e- with each of the three H atoms, resulting in a total of three joined pairs of electrons. The ammonia molecule takes a trigonal pyramidal form attributed to the arrangement of the outer electrons according to its Electron pair Beverage cup structure. In the dot symbol representation of NH3, the N atom is surrounded by three spots, each representing a pair of united electrons with a hydrogen atom.
