Electron pair dot arrangement for ammonia is a representation of the valence electrons surrounding the nitrogen atom.
The Lewis point arrangement in the case of NH3 displays that the nitrogen atom connects one pair of electrons with each of the three H atoms, resulting in a complete of a trio joined pairs of electrons.
The NH3 molecule adopts a three-sided pyramid-like form because of the arrangement of the outer electrons according to its Electron pair Beverage cup structure.
In the Lewis dotpoint representation of NH3, the N atom is enveloped by three dots, each representing a pair of shared electrons with a hydrogen atom.
