Electron pair Beverage cup structure in the case of ammonia is a representation of the valence electrons surrounding the nitrogen atom.
The dot dot arrangement for NH3 reveals that the N atom unites a solitary pair of electrons with each of the three hydrogen atoms, resulting in a complete of 3 joined pairs of electrons.
The ammonia
molecule adopts a trigonal pyramidal shape because of the arrangement of the valence electrons according to its Lewis dot arrangement.
In the Lewis symbol depiction of NH3, the N atom is enveloped by three dots,
each representing a pair of joined electrons with a H atom.
