Electron pair Beverage cup structure for NH3 is shown by the valence electrons surrounding the N atom.
The Lewis dot structure in the case of ammonia reveals that the nitrogen atom joins one pair of electrons with each of the three hydrogen atoms, resulting in a overall of a trio connected pairs of electrons.
The ammonia molecule takes a trigonal pyramidal shape due to the placement of the valence electrons according to its Lewis Beverage cup structure.
In the Lewis symbol depiction of NH3, the nitrogen atom is enveloped by three points, each representing a pair of joined electrons with a H atom.
