Lewis
Beverage cup arrangement for NH3 is portrayed by the outer electrons surrounding the N atom.
The Lewis dot structure in the case of ammonia unveils that the nitrogen atom unites a solitary pair of e- with each of the three hydrogen atoms, resulting in a total of 3 joined pairs of electrons.
The NH3 molecule takes a three-sided pyramid-like shape attributed to the placement of the valence electrons according to its Electron pair Beverage cup arrangement.
In the dot symbol representation of ammonia, the nitrogen atom is encircled by three points, each representing a pair of shared electrons with a hydrogen atom.
