Radical Placement

When you have a radical, how do you know where to place the one extra electron? Is it just in the place that would ensure the most stability about the central atom?

In most cases there only ends up being one place for the radical/extra electron to be placed- I can't really think of a molecule where you have multiple options. Usually if we have say and nh3 ion, the extra electron goes on nitrogen because hydrogen can't physically take on another electron.

It typically goes on the element like Nitrogen, in which the placement of the radical ensures stability of the atom. See whichever placement gives you a formal charge of 0 for each atom.

The radical goes on the element that would have the formal charge closest to zero when the electron is added!
