Lewis dot arrangement for NH3 is portrayed by the valence electrons surrounding the nitrogen atom. The dot dot structure in the case of NH3 unveils that the nitrogen atom joins one pair of electrons with each of the three hydrogen atoms, resulting in a overall of three connected pairs of electrons. The ammonia molecule takes a trigonal pyramidal structure due to the distribution of the valence electrons according to its Electron pair dot arrangement. In the Lewis symbol depiction of ammonia, the nitrogen atom is surrounded by three dots, each representing a pair of connected electrons with a H atom.
