How many lone pairs of electrons? Yahoo Answers

The lone pairs associated with each oxygen atom are there to give each oxygen atom a full octet. Count the electrons in the lone pairs and the electrons shared by each oxygen atom. You will see that each atom has 8 electrons. If you’re particularly observant you might be asking- isn’t there another way for each atom to have 8 electrons? Why, yes there is! What if we had drawn the structure
