Lewis Theory of Bonding Chemistry LibreTextsElectron pair dot structure in the case of NH3 is shown by the valence electrons surrounding the N atom.
The Lewis dot arrangement for ammonia exhibits that the N atom unites 1 pair of electrons with each of the three hydrogen atoms, resulting in a overall of three united pairs of electrons.
The ammonia molecule adopts a three-sided pyramid-like form due to the placement of the outer electrons
according to its Lewis Beverage cup structure.
In the dot symbol depiction of NH3, the nitrogen atom is enveloped by three spots, each representing a pair of joined electrons with a hydrogen atom.
