Electron pair Beverage cup structure for NH3 is shown by the
valence electrons surrounding the N atom.
The Lewis dot arrangement in the case of NH3 reveals that the nitrogen atom shares one pair of electrons with each of the three H atoms, resulting in a overall of three joined pairs of electrons.
The ammonia molecule takes a trigonal pyramidal shape attributed to the distribution of the outer electrons according to its Lewis dot arrangement.
In the dot symbol depiction of ammonia, the nitrogen atom is encircled by three points, each representing a pair of united electrons with a H atom.
