In molecular orbital theory, it states that there are two types
of formation, one is the bonding molecular orbital, and another is
the anti-bonding molecular orbital.
I understand about the part on the superposition of wave affects
how the electrons will bond, but just wanna clarify:
In a given hydrogen molecule, take for example a sigma bond between
the hydrogen atoms, will there be a bonding AND an antibonding
molecular orbital formation?
Or is the formation of molecules will just have either the bonding
or antibonding outcome. When its bonding, then it is bonding, and
when its antibonding, it is antibonding.
It seems like the second one, having read about the differences of
Hydrogen and Helium, it seems the reason why Hydrogen bonds is
because of the bonding molecular orbital, and Helium, due to it
being a noble gas, does an antibonding molecular orbital. But
what's the rationale behind it?
