Electron pair Beverage cup structure for ammonia is shown by the outer electrons surrounding the N atom.
The Lewis point arrangement for ammonia reveals that the N atom unites 1 pair of electrons with each of the three hydrogen atoms, resulting in a total of 3 united pairs of electrons.
The ammonia molecule takes a trigonal pyramidal form due to the distribution of the outer electrons according to its Electron pair dot structure.
In the dot symbol representation of NH3, the N atom is encircled by three spots, each representing a pair of connected electrons with a hydrogen atom.
