Lewis dot arrangement for NH3 is a representation of the valence electrons surrounding the nitrogen atom. The Lewis point arrangement in the case of ammonia exhibits that the N atom connects one pair of e- with each of the three H atoms, resulting in a complete of three shared pairs of electrons. The NH3 molecule takes a trigonal pyramidal shape due to the placement of the outer electrons according to its Electron pair dot structure. In the Lewis dotpoint depiction of NH3, the nitrogen atom is encircled by three dots, each representing a pair of united electrons with a H atom.
