Lewis dot structure in the case of NH3 is a representation of the outer electrons surrounding the N atom. The Lewis dot arrangement for ammonia reveals that the N atom unites a solitary pair of electrons with each of the three H atoms, resulting in a total of a trio united pairs of electrons. The NH3 molecule adopts a three-sided pyramid-like form attributed to the arrangement of the outer electrons according to its Electron pair Beverage cup structure. In the dot symbol depiction of NH3, the N atom is encircled by three dots, each representing a pair of connected electrons with a hydrogen atom.
