Electron pair dot structure for NH3 is shown by the valence electrons surrounding the nitrogen atom. The dot point arrangement for ammonia unveils that the nitrogen atom joins one pair of electrons with each of the three hydrogen atoms, resulting in a total of three connected pairs of electrons. The ammonia molecule takes a trigonal pyramidal shape attributed to the arrangement of the outer electrons according to its Electron pair dot structure. In the Lewis symbol depiction of NH3, the N atom is encircled by three points, each representing a pair of connected electrons with a hydrogen atom.
