Electron pair Beverage cup structure in the case of NH3 is illustrated by the outer electrons surrounding the N atom.
The dot dot arrangement for NH3 displays that the nitrogen atom connects 1 pair of e- with each of the three H atoms, resulting in a total of three joined pairs of electrons.
The ammonia molecule takes a three-sided
pyramid-like form because of the placement of the valence electrons
according to its Electron pair dot arrangement.
In the dot dotpoint depiction of ammonia, the N atom is surrounded by three points, each representing a pair of joined electrons with a H atom.
