KO2 is a superoxide in which, only one electron is released from the dioxygen atom and a superoxide ion is represented as O2- . So, in KO2 the oxygen atoms bear -1/2 oxidation state and they also behave as a free radical species, having an unpaired electron.

We know that a molecule becomes paramagnetic due to the presence of unpaired electrons. Hence, KO2 behaves as paramagnetic molecule.

KO2 means K+O2- here O2- is paramagnetic .according to molecular orbital theory O2- has one antibonding orbital is partial fill.i.e 1sigma s^2 , 1sigma*s^2,2sigma s^2,2sigma*s^2, 2sigma. px^2, pi 2py^2=pi2pz^2, pi*2py^2=pi*2pz^1 we show last in configuration of O2- has partially filled so KO2 is paramagnetic.
