104 Writing Lewis Structures Chemistry LibreTextsElectron pair Beverage cup structure in the case of ammonia is a representation of the outer electrons surrounding the N atom.
The dot point arrangement in the case of NH3 unveils that the N atom joins a solitary pair of electrons with each of the three hydrogen atoms, resulting in a overall of a trio connected pairs of electrons.
The NH3 molecule takes a trigonal pyramidal form because of the distribution of the outer electrons according to its Lewis Beverage cup structure.
In the dot symbol depiction of NH3, the N atom is enveloped by three dots, each representing a pair of joined electrons with a hydrogen atom.
