Write the energy level diagram of oxygen molecule.

Explanation

Atomic number of oxygen is `8:1s^(2)2s^(2),2P^(4)`

Molecular orbital diagram of oxygen molecule
a) Bond order `=(8-4)/(2)=2`
b) Electronic confguration of oxygen molecule is
`KKsigma2s^(2)sigma^(**)2s^(2)sigma2p_(z)^(2)" "pi2p_(x)^(2)" "pi2p_(y)^(2)" "pi^(**)2p_(x)^(1)" "pi^(**)2p_(y)^(1)`
c) Magnetic property : Paramagnetic.
