Dear student,
According to the molecular orbital diagram for O2:
No. of electrons in BO=8 :No. of electrons in AO=4
O2: no of unpaired electrons= 2 so it is paramagnetic
O2+:no of unpaired electrons= 1so it is paramagnetic
O2-:no of unpaired electrons= 1 so it is paraamagnetic
(O2)2-:no of unpaired electrons=0so it is diamagnetic
