WebSep 2, 2024 · Find the number of lone pairs on the central atom by subtracting the number of valence electrons on bonded atoms (Step 2) from the total number of valence electrons … WebThe pair of electrons left without forming covalent bonds in the outermost valence shell is known as lone pair of electrons. Since the p-orbital is active in the pi bond, this lone pair can’t be in a p orbital. Instead, it is in the plane of the ring, at 90 degrees to the pi bond.
