Molecular orbital configuration of
O 2 + _ _ 1 s 2 _ _ 1 s 2 _ 2 s 2 _ _ 2 s 2 _ 2 p z 2 � 2 p y 2 � _ 2 p x 1 � _ 2 p y 1 _ Paramagnetic
Bond order = 10 _ 5 2 = 2.5
C 2 _ _ 1 s 2 _ _ 1 s 2 _ 2 s 2 _ _ 2 s 2 _ 2 p z 2 � 2 p y 2 _ Diamagnetic
Bond order = 8 _ 4 2 = 2
C 2 + _ _ 1 s 2 _ _ 1 s 2 _ 2 s 2 _ _ 2 s 2 _ 2 p z 2 � 2 p y 1 _ Paramagnetic
Bond order = 7 _ 4 2 = 1.5
NO _ _ 1 s 2 _ _ 1 s 2 _ 2 s 2 _ _ 2 s 2 _ 2 p z 2 � 2 p y 2 � _ 2 p x 1 _ Paramagnetic
Bond order = 10 _ 5 2 = 2.5
NO + _ _ 1 s 2 _ _ 1 s 2 _ 2 s 2 _ _ 2 s 2 _ 2 p z 2 � 2 p x 2 � 2 p y 2 _ Diamagnetic
Bond order = 10 _ 4 2 = 3
N 2 _ _ 1 s 2 _ _ 1 s 2 _ 2 s 2 _ _ 2 s 2 � 2 p x 2 � 2 p y 2 _ 2 p z 2 _ Paramagnetic
Bond order = 10 _ 4 2 = 3
N 2 + _ _ 1 s 2 _ _ 1 s 2 _ 2 s 2 _ _ 2 s 2 � 2 p x 2 � 2 p y 2 _ 2 p z 1 _ Paramagnetic
Bond order = 9 _ 4 2 = 2.5
