Electron pair dot arrangement for ammonia is shown by the valence electrons surrounding the nitrogen atom. The dot dot arrangement for ammonia unveils that the nitrogen atom unites one pair of e- with each of the three H atoms, resulting in a overall of three joined pairs of electrons. The ammonia molecule takes a trigonal pyramidal form due to the placement of the outer electrons according to its Electron pair dot structure. In the dot dotpoint representation of NH3, the N atom is encircled by three spots, each representing a pair of shared electrons with a H atom.
