Lewis dot arrangement for NH3 is a representation of the valence electrons surrounding the
N atom.
The dot dot arrangement in the case of NH3 displays that the N atom unites one pair of electrons with each of the three hydrogen atoms, resulting in a complete of a trio joined pairs of electrons.
The NH3 molecule adopts a three-sided pyramid-like structure because
of the distribution of the
valence electrons according to its Electron pair dot arrangement.
In the dot symbol depiction of NH3, the nitrogen atom is enclosed by three dots, each representing a pair of shared electrons with a H atom.
