Lewis dot arrangement for ammonia is a representation of the outer electrons surrounding the nitrogen atom.
The dot point structure for NH3 displays
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 three-sided pyramid-like shape because of the placement of the valence electrons according to its Electron pair dot structure.
In the dot dotpoint representation of ammonia, the nitrogen atom is surrounded by three points, each representing a pair of joined electrons with a H atom.
