9 Covalent Bonding Chemistry LibreTextsElectron pair Beverage cup structure in the case of ammonia is depicted by the outer electrons surrounding the N atom.
The Lewis dot structure in the case of NH3 unveils that the nitrogen atom joins 1 pair of e- with each of the three hydrogen atoms, resulting in a complete of a trio joined pairs of electrons.
The ammonia molecule adopts a three-sided pyramid-like structure due to the arrangement of the valence electrons according to its Electron pair dot arrangement.
In the Lewis symbol depiction of NH3, the N atom is enclosed by three dots, each representing a pair of united electrons with a hydrogen atom.
