AI Thread Summary
Fluorine uses 2P orbitals for bonding in the HF molecular orbital model due to its electron configuration of 1S2 2S2 2P5. The filled 2S orbital does not participate in bonding, allowing the unpaired 2P electrons to form bonds. While hybridization is often discussed, it is not necessary to apply it to molecular orbital theory. In the context of HF bonding, the bonding electrons are primarily in the 2P orbital rather than in an SP3 hybridized state. Understanding the role of these orbitals is crucial for accurately describing the bonding in HF.

Can you bond using suborbitals that are already filled?

OK i get it. I should never use hybridization to account for MO theory.
But wait . F become SP3 hybridization when bonding. Please tell me!
Which orbital does the bonding electron lie in F atom, SP3 or P orbital?
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
