The Lewis dot structure for molecular oxygen (O2) is shown below. Note, O2 exists as drawn with unpaired electrons on each oxygen atom. Using your understanding of formal charge, what is the charge on the oxygen atoms? F=Z–(1/2)S–U, where F=formal charge, Z=atomic number, S=number of shared electrons, U=number of unshared electrons.

The carbon highlighted in green is _____valent.

Rank in order of longest to smallest bond distances.
