Electron pair Beverage cup arrangement for ammonia is shown by the valence electrons surrounding the N atom.
The dot dot arrangement in the case of NH3 unveils that the nitrogen atom joins 1 pair of e- with each of the three H atoms, resulting in a
overall of 3 joined pairs of electrons.
The ammonia molecule adopts a three-sided pyramid-like shape because of the distribution of the valence electrons according to its Lewis dot structure.
In the dot dotpoint depiction of ammonia, the nitrogen atom is enclosed by three dots, each representing a pair of joined electrons with a H atom.
