Lewis Beverage cup arrangement for ammonia is portrayed by the outer electrons surrounding the N atom. The dot dot arrangement for ammonia unveils that the nitrogen atom unites 1 pair of electrons with each of the three hydrogen atoms, resulting in a overall of 3 shared pairs of electrons. The NH3 molecule takes a trigonal pyramidal shape due to the placement of the outer electrons according to its Electron pair dot arrangement. In the Lewis symbol representation of NH3, the nitrogen atom is enclosed by three points, each representing a pair of connected electrons with a H atom.
