where do you place the unpaired electron of a free radical?

How do you know which atom the unpaired electron goes to? e.g. ClO in 3.57 - why is the unpaired electron on Cl and not on O?

I think Chlorine gets the unpaired electron because Oxygen is more electronegative (meaning Oxygen wants its octet more than Chlorine does). Thus you would first complete the octet for Oxygen before distributing the electrons around Chlorine.

The atom that is least electronegative gets the unpaired electron. Periodic trends tell us that electronegativity decreases as you go down a group, and increases left to right across a period. Cl is less electronegative.
