Write the valence molecular orbital configuration of Ne2+. The fill order for Ne is as follows: σ2s σ*2s σ2p π2p π2p π*2p π*2p σ*2p What is the bond order of Ne2 + according to molecular orbital theory?

Valence orbital configuration of Ne2^+

σ2s2 σ*2s2 σ2p2 π2p2 π2p2 π*2p2 π*2p2 σ*2p1

Bond order = 0.5

Explanation:

Ne2^ + ought to have 19 electrons. If the inner or coire electrons of the molecule are shown as KK, then the full molecular orbital configuration of the molecule is

KK σ2s2 σ*2s2 σ2p2 π2p2 π2p2 π*2p2 π*2p2 σ*2p1

Hence the bond order is 1/2 (bonding - anti bounding) electrons

Bonding electrons = 10

Anti bonding electrons = 9

1/2 (10-9) = 0.5
