KO2 means K^+ and O2^- ions
for O2^- ions ,
according to molecular orbital theory .
if one or more molecular orbital is /are singly occupied , the substance is paramagnetic .
here , O2^- configuration ,
= Sigma 1s² , sigma* 1s², Sigma 2s², Sigma* 2s² , sigma 2px² , π 2py²≈ π2pz² , π*2py² ≈ π*2pz¹
here we see in one antibonding orbital is singly occupied so, O2^- is paramagnetic hence , KO2 is paramagnetic .

KO2 is a superoxide in which , only one electron is released from the dioxygen atom and a superoxide ion is represented as 02 .
KO2 is a superoxide which contains odd
number of electrons ( unpaired
electrons ) . Thus Ko2 is paramagnetic .
