35 Lewis Structures and Covalent Bonding Chemistry LibreTexts
Lewis dot structure in the case of NH3 is depicted by the outer electrons surrounding the N atom. The dot dot arrangement in the case of ammonia displays that the nitrogen atom connects one pair of e- with each of the three hydrogen atoms, resulting in a complete of 3 shared pairs of electrons. The NH3 molecule adopts a trigonal pyramidal shape because of the arrangement of the outer electrons according to its Electron pair dot arrangement. In the dot symbol representation of ammonia, the N atom is surrounded by three points, each representing a pair of united electrons with a H atom.
