Kevin draws a lewis structure for the molecule of ozone, o3. later on that day, he draws another one for a friend to show what he's learned in school. when he compares the two drawings, he notices they look different. he runs to the teacher the next day to ask her which one is right. smiling, she answers, "they're both correct." explain why this is.

The most important part of a lewis structure is that it's number of valence electrons matches the number needed for the atom(s). Because lewis structures are drawn with many "slots" for valence electrons, they can be assigned in a loose order as long as they do not inherently change the shape or number of electrons for the atom. Therefore different lewis structures can be formed, just keep the variables the same.
