hi all,
i am now studying the Molecular Orbital theory. when i comparing the MO between Li2 and F2, the pattern is different and the books said this is because it is due to the mixing of orbital between 2s and 2f in Lithium.
Why the energy different between 2s and 2f in Flourine and Oxygen is higher than that of Lithium to Nitrogen, Although that F and O have higher electronegative than Li? thanks!
