Electron pair Beverage cup structure for NH3 is a representation of the outer electrons surrounding the nitrogen atom.
The Lewis dot structure for ammonia unveils that the nitrogen atom joins 1 pair of e- with each of the three hydrogen atoms, resulting in a total of three united pairs of electrons.
The ammonia molecule takes a three-sided pyramid-like shape due to the arrangement of the valence electrons according to its
Lewis dot arrangement.
In the dot dotpoint depiction of ammonia, the N
atom is enclosed by three spots, each representing a pair of joined electrons with a hydrogen atom.
