So why  the bond energy of H2 is higher than that of F2 ..? ??
Even there is a lots of difference....
H2 - 436 kJ/mol
F2 -  158 kJ/mol

Lone pair repulsion drives nuclei farther apart (bond length of F2 is about 1.41 Å, for H2 it's about 0.74 Å), overlap is poor.

still we mix up ideas. i don't think you got it, judging from your question.

you totally mix up bond energies and absolute energies.

I just got it dude..
Listen what i've learned ( if i am wrong then please correct me)

Bond energy depend upon the energy difference between Atomic orbital and molecular orbital, it does not depend upon absolute energy of an orbital.
