In chlorine monoxide ClO, when Cl has the radical, the formal charge of Cl is +1 and the formal charge of O is -1. Right? If O is given the radical then the formal charges are 0. Why does Cl have the radical?

There is debate on this answer.

The link below from NIST has the asterisk (which notes the radical) is on the O, not Cl.

https://webbook.nist.gov/cgi/inchi?ID=C ... &Mask=1000

Unpaired e- on oxygen results in a formal charge of zero for both the O and the Cl atoms.

We will defer to formal charge and NIST and take the answer as an unpaired electron on the oxygen atom.

Good question.
