Lewis dot structure for ammonia is depicted by the valence electrons surrounding the nitrogen atom. The dot point arrangement for NH3 exhibits that the nitrogen atom joins one pair of electrons with each of the three hydrogen atoms, resulting in a complete of a trio connected pairs of electrons. The ammonia molecule adopts a three-sided pyramid-like form because of the placement of the outer electrons according to its Electron pair dot arrangement. In the dot dotpoint representation of ammonia, the nitrogen atom is enclosed by three spots, each representing a pair of shared electrons with a hydrogen atom.
