Electron pair Beverage cup structure in the case of ammonia is illustrated by the valence electrons surrounding the N atom.
The dot point structure for ammonia reveals that the N atom joins 1 pair of e- with each of the three H atoms, resulting in a overall of 3 connected pairs of electrons.
The ammonia molecule adopts a three-sided pyramid-like shape because of the
placement of the outer electrons according to its Electron pair dot structure.
In the Lewis symbol depiction of NH3, the N atom is enveloped by three spots, each representing a pair of shared electrons with a hydrogen atom.
