Electron pair dot structure for ammonia is a representation of the valence electrons surrounding the N atom. The dot point structure for ammonia reveals that the N atom joins 1 pair of e- with each of the three hydrogen atoms, resulting in a complete of three shared pairs of electrons. The ammonia molecule takes a three-sided pyramid-like shape because of the placement of the outer electrons according to its Electron pair dot arrangement. In the Lewis dotpoint representation of ammonia, the nitrogen atom is surrounded by three dots, each representing a pair of joined electrons with a hydrogen atom.
