Lewis Beverage cup arrangement for ammonia is shown by the valence electrons surrounding the nitrogen atom.
The dot dot arrangement in the case of NH3 exhibits that the nitrogen atom unites a solitary pair of e- with each of the three H atoms, resulting in a complete of 3 connected pairs of electrons.
The NH3 molecule adopts a trigonal pyramidal shape attributed to the arrangement of the outer electrons according to its Electron pair dot arrangement.
In the dot dotpoint representation of NH3, the nitrogen atom is enclosed by three points, each representing a pair of joined electrons with a H atom.
