Electron pair dot structure in the case of NH3 is a representation of the valence electrons surrounding the N atom. The Lewis dot structure for NH3 reveals that the N atom joins 1 pair of e- with each of the three hydrogen atoms, resulting in a complete of 3 shared pairs of electrons. The NH3 molecule adopts a trigonal pyramidal structure attributed to the placement of the valence electrons according to its Lewis dot arrangement. In the dot symbol representation of ammonia, the nitrogen atom is surrounded by three dots, each representing a pair of connected electrons with a hydrogen atom.
