molecular orbital of o2,
Hi Sandip,
A molecule of oxygen has 16 electrons and is formed by the combination of two atoms of oxygen each having 8 electrons. Now the electronic configuration of atomic oxygen is 1s2, 2s2, 2p4. In a molecule of oxygen, the atomic orbitals get mixed to form molecular orbitals. The number of molecular orbitals is equal to the sum of the atomic orbitals.
The electronic configuration becomes:
(s1s)2 (s*1s)2 (s2s)2 (s*2s)2 (s2pz)2 (.png)

)()The molecular orbital energy level diagram of O2 molecule can be drawn as: .png)
Hope, this answer helps you.
Best wishes!
