Electron pair Beverage cup structure for NH3 is a representation of the valence electrons surrounding the nitrogen
atom.
The dot point arrangement in the case of NH3 unveils that the N
atom unites a solitary pair of e- with each of the three hydrogen atoms, resulting in a total of 3 shared pairs of electrons.
The ammonia molecule takes a three-sided pyramid-like shape due to the distribution of the outer electrons according to its Lewis Beverage cup structure.
In the dot dotpoint representation of ammonia, the nitrogen atom is enveloped by
three dots, each representing a pair of joined electrons with a hydrogen atom.
