Lewis Dot Structures Chemistry LibreTexts
Electron pair dot arrangement in the case of NH3 is depicted by the outer electrons surrounding the nitrogen atom. The Lewis dot arrangement for NH3 displays that the nitrogen atom connects a solitary pair of e- with each of the three hydrogen atoms, resulting in a overall of a trio shared pairs of electrons. The ammonia molecule takes a three-sided pyramid-like structure because of the placement of the valence electrons according to its Electron pair Beverage cup structure. In the dot symbol representation of ammonia, the nitrogen atom is encircled by three dots, each representing a pair of connected electrons with a hydrogen atom.
