Electron pair Beverage cup arrangement for NH3 is a representation of the outer electrons surrounding the N atom.
The dot dot structure for ammonia reveals that the N atom unites 1 pair of e- with each of the three hydrogen atoms, resulting in a complete of 3 united pairs of electrons.
The ammonia molecule adopts a three-sided pyramid-like form because of the placement of the valence electrons according to its Lewis dot arrangement.
In the dot dotpoint representation of ammonia, the nitrogen atom is enclosed by three spots, each representing a pair of joined electrons with a H atom.
