35 Lewis Structures and Covalent Bonding Chemistry LibreTextsLewis dot structure for NH3 is portrayed by the outer electrons surrounding the N atom.
The Lewis dot arrangement in the case of ammonia reveals that the N atom joins one pair of e- with each of the three hydrogen atoms, resulting in a total of 3 joined pairs of electrons.
The NH3 molecule adopts a three-sided pyramid-like form because of the placement of the valence electrons according to its Electron pair dot structure.
In the dot symbol depiction of ammonia, the N atom is enveloped by three dots, each representing a pair of connected electrons with a hydrogen atom.
