Lewis Beverage cup structure for NH3 is shown by the valence electrons surrounding the nitrogen atom.
The Lewis dot arrangement for ammonia unveils that the N atom shares 1 pair of electrons with each of
the three hydrogen atoms, resulting in a complete of 3 joined pairs of electrons.
The ammonia molecule takes a three-sided pyramid-like form because of the distribution of the valence electrons according to its Electron pair dot structure.
In the dot dotpoint depiction of ammonia, the nitrogen atom is enveloped by three dots, each representing a pair of shared electrons with a hydrogen
atom.
