Electron pair Beverage cup structure in the case of NH3 is depicted by the valence electrons surrounding the N atom.
The Lewis point structure for ammonia reveals that the N atom unites 1 pair of electrons with each of the three H atoms, resulting in a total of three connected pairs of electrons.
The NH3 molecule adopts a trigonal pyramidal structure due to the distribution of the valence electrons according to its Lewis dot arrangement.
In the dot dotpoint depiction of ammonia, the nitrogen atom is enclosed by three points, each representing a pair of united electrons with a H atom.
