While dealing with the Lewis structure for ozone, most of the explanations show the electron distribution around the 3 oxygen atoms with a single and double bond.
But if you count the number of valence electrons of the middle oxygen atom, it will add to 5 valence electrons only, but the number of valence electrons of an oxygen atom is 6.
Similarly, the oxygen atom with a single bond in ozone, is being shown with 6 valence electrons plus one single bond, which accounts for 7 valence electrons, which does not tally with the expected number of 6 valence electrons.
Can someone please explain why this discrepancy has been permitted? Or what did we miss to consider?
