Electron pair dot arrangement in the case of NH3 is illustrated by the valence electrons surrounding the N atom.
The dot dot arrangement
for ammonia reveals that the N atom unites 1 pair of electrons with each of the three hydrogen atoms, resulting in a complete of a trio joined pairs of electrons.
The NH3 molecule adopts a trigonal pyramidal form attributed to the placement of the valence electrons according to its Electron pair Beverage cup arrangement.
In the Lewis symbol depiction of NH3, the nitrogen atom is enclosed by three dots, each representing a pair of joined electrons with a hydrogen atom.
