Electron pair Beverage cup structure in the case of ammonia is shown by the valence electrons surrounding the N atom. The Lewis point arrangement for NH3 displays that the nitrogen atom unites a solitary pair of electrons with each of the three hydrogen atoms, resulting in a overall of three shared pairs of electrons. The NH3 molecule takes a trigonal pyramidal form due to the arrangement of the valence electrons according to its Electron pair Beverage cup structure. In the Lewis symbol representation of ammonia, the N atom is enveloped by three dots, each representing a pair of united electrons with a hydrogen atom.
