95 Covalent Bonding Lewis Structure Chemistry LibreTexts
Lewis dot arrangement in the case of NH3 is shown by the valence electrons surrounding the nitrogen atom. The dot dot arrangement in the case of NH3 unveils that the N atom unites one pair of e- with each of the three H atoms, resulting in a complete of three joined pairs of electrons. The ammonia molecule takes a trigonal pyramidal structure due to the arrangement of the outer electrons according to its Electron pair dot arrangement. In the dot symbol representation of NH3, the nitrogen atom is enclosed by three spots, each representing a pair of united electrons with a hydrogen atom.
