45 Lewis Dot and Bonding Chemistry LibreTexts
Lewis Beverage cup arrangement for ammonia is a representation of the valence electrons surrounding the nitrogen atom. The dot point arrangement for NH3 displays that the nitrogen atom shares 1 pair of e- with each of the three H atoms, resulting in a overall of a trio joined pairs of electrons. The ammonia molecule adopts a three-sided pyramid-like structure attributed to the distribution of the outer electrons according to its Lewis dot structure. In the dot symbol representation of ammonia, the N atom is surrounded by three points, each representing a pair of united electrons with a hydrogen atom.
