Lewis dot arrangement for ammonia is illustrated by the valence electrons surrounding the nitrogen atom. The Lewis point structure for ammonia exhibits that the N atom unites a solitary pair of e- with each of the three hydrogen atoms, resulting in a overall of three joined pairs of electrons. The NH3 molecule adopts a three-sided pyramid-like structure attributed to the placement of the outer electrons according to its Electron pair Beverage cup structure. In the Lewis symbol depiction of ammonia, the N atom is enclosed by three dots, each representing a pair of shared electrons with a H atom.
