Lewis Beverage cup structure for ammonia is depicted by the valence electrons surrounding the N atom. The Lewis point arrangement for NH3 displays that the nitrogen atom unites a solitary pair of electrons with each of the three hydrogen atoms, resulting in a total of three joined pairs of electrons. The NH3 molecule adopts a three-sided pyramid-like form due to the placement of the outer electrons according to its Electron pair dot arrangement. In the dot symbol depiction of ammonia, the N atom is encircled by three dots, each representing a pair of connected electrons with a H atom.
