Electron pair Beverage cup structure in the case of NH3 is portrayed by the outer electrons surrounding the nitrogen atom.
The
dot point arrangement for NH3 reveals that the N atom shares 1 pair of electrons with each of the three hydrogen atoms, resulting in a total of three shared pairs of electrons.
The NH3 molecule adopts a trigonal pyramidal form due to the placement of the valence electrons according to its Electron pair dot structure.
In the Lewis symbol depiction of ammonia, the nitrogen atom is encircled by three points, each representing a pair of joined electrons with a H atom.
