I had a question that popped up in my head. In case of organometallic complexes loss of an electron from the d orbitals of the central metal leads to an increase in the oxidation state. But loss of an electron also occurs incase of free radical generation. Incase of mass spectrometry also we see the electron loss resulting formation of cation radical. So what shall we consider loss of the pair of electrons leading to increase in oxidation state or just and electron?

Please help me out.
