Formal Charge W/ Radicals

How do you calculate formal charge when considering radicals?

It would still be the same formula to solve for formal charge, but you can tell the atom is radical if it has an unpaired electron or odd number of electrons. For example, CH3 would be a radical since it is 4+3= 7 electrons and when you make the Lewis structure it shows a lone electron.

Same formula of Formal Charge = Valence - (Lone Pair e- + 1/2Bonded e-), so for the # of lone pair e-, it would just be an odd number when dealing with radicals
