Electron pair Beverage cup arrangement in the case of NH3 is illustrated
by the outer electrons surrounding the N
atom.
The Lewis point structure for NH3 exhibits that the nitrogen atom shares a solitary pair of electrons with each of the three hydrogen atoms, resulting in a overall of three united pairs of electrons.
The ammonia molecule takes a trigonal pyramidal form due to the distribution of the valence electrons according to its Lewis dot arrangement.
In the dot symbol depiction of NH3, the N atom is enclosed by three dots, each representing a pair of joined electrons with a H atom.
