Electron pair dot structure in the case of ammonia is a representation of the valence electrons surrounding the N atom.
The dot point structure in the case of ammonia
reveals that the nitrogen atom unites 1 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 three-sided pyramid-like form due to the distribution of the outer electrons according to its
Electron pair Beverage cup structure.
In the dot dotpoint depiction of ammonia, the nitrogen atom is enveloped by three points, each representing a pair of united electrons with a H atom.
