Are there any polar halogens?

All halogens are nonpolar, no exceptions.

All halogens are diatomic molecules in reality at #0^@ "C"# and #"1 atm"#, i.e. #"F"_2(g)#, #"Cl"_2(g)#, #"Br"_2(l)#, #"I"_2(s)#. They are linear as a result, and contain two identical atoms. There is no asymmetry to speak of, and so, there is no polarity to speak of, since there is zero electronegativity difference.

What must the oxidation states of each halogen atom be in their molecular form, then? (If #x + x = 0#, what is #x#?)
