Electron pair Beverage cup arrangement in the case of NH3 is shown by the valence electrons surrounding the nitrogen atom.
The dot dot structure for NH3 exhibits that the nitrogen atom unites a solitary pair of e- with each of the three hydrogen atoms, resulting in a complete of a trio shared pairs of electrons.
The NH3 molecule takes a trigonal pyramidal shape due to the arrangement of the valence electrons according to its Electron pair Beverage cup arrangement.
In the Lewis symbol depiction of NH3, the nitrogen atom is enveloped by three points, each representing a pair of united electrons with a H atom.
