12 Lewis Theory of Bonding Chemistry LibreTextsElectron pair dot arrangement in the case of NH3
is portrayed by the outer electrons surrounding the N atom.
The dot point structure for ammonia exhibits that the nitrogen atom joins a solitary pair of e- with each of the three H atoms, resulting in a complete of 3 shared pairs of electrons.
The NH3 molecule takes a three-sided pyramid-like shape due to the distribution of the valence electrons according to its Electron pair Beverage cup arrangement.
In the Lewis dotpoint representation of ammonia, the nitrogen atom is enclosed by three spots, each representing a pair of shared electrons with a hydrogen atom.
