Electron pair dot structure in the case of ammonia is illustrated by the valence electrons surrounding the N atom. The dot dot structure in the case of NH3 unveils that the N atom joins a solitary pair of electrons with each of the three hydrogen atoms, resulting in a complete of a trio joined pairs of electrons. The ammonia molecule adopts a three-sided pyramid-like form due to the placement of the valence electrons according to its Lewis dot arrangement. In the dot symbol depiction of ammonia, the nitrogen atom is encircled by three points, each representing a pair of connected electrons with a hydrogen atom.
