Lewis Beverage cup structure in the case of NH3 is a representation of the outer electrons surrounding the N atom. The Lewis dot structure in the case of ammonia unveils that the nitrogen atom joins 1 pair of electrons 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 structure. In the dot symbol representation of ammonia, the N atom is surrounded by three points, each representing a pair of joined electrons with a H atom.
