Question

Complete the valence molecular-orbital diagram for oxygen, O, Answer Bank

Answer 1

σ and σ* orbital can have maximum of 2 electrons

π and π* orbital can have maximum of 4 electrons

1 O atom have 8 electrons

Here, number of O is 2

so, total number of electrons in O2 is 16

So, total number of electrons to fill is 16

order of filling of orbitals is:

σ1s σ*1s σ2s σ*2s σ2p π2p π*2p σ*2p

Lets fill the orbital

the filled orbital is σ1s2 σ*1s2 σ2s2 σ*2s2 σ2p2 π2p4 π*2p2
