Lewis dot arrangement for NH3 is shown by the valence electrons surrounding the N atom.
The Lewis dot arrangement for NH3 displays that the nitrogen atom connects a solitary pair of e- with each of the three H atoms, resulting in a total of 3 connected pairs of electrons.
The ammonia molecule takes a three-sided pyramid-like structure attributed to the placement of the outer electrons according to its Electron pair Beverage cup arrangement.
In the dot symbol depiction of ammonia, the nitrogen atom is enveloped by three dots, each representing a pair of united electrons with a H atom.
