    For hybridization to occur, must electron always be promoted? Is it possible for hybridization to occur without the promotion of an electron?

    Secondly, if electrons DO need to be promoted, must there be at least one completely empty orbital in the shell it is being promoted to?
    For example, say an electron is promoted from 2s to one of the 2p orbitals. What if every 2p orbital already had 1 electron? (a configuration such as ). Would an electron still be promoted to one of the p orbitals to make a configuration like

    I'm not entirely sure what you mean. Usually people don't think of hybrid orbitals as involving electrons being "promoted" from, for example, an S orbital to a P orbital. Hybridization occurs when the S and some of the P orbitals combine into a new set of orbitals that are equal in energy.

    well, I'm talking about the promotion of the electrons that happens BEFORE* hybridization... Does this promotion always happen? or is it confined to certain instances?

    EDIT * "Before" isn't probably an accurate word . It all happens in an instant.. But just for clarity, let's say the electrons are promoted before hybridization. The key thing is... are electrons ALWAYS promoted when hybridization occurs.

    I really don't understand what you're talking about here, the electons aren't promoted the orbitals merge with eachother and form an entirely new orbital. you c
    everything is mathematical.

    Again, I have never heard orbital hybridization described as involving promotion of electrons. Did someone tell you that hybridization involved electron promotion?

    Although personally I hate "hybrid orbitals," as they're mostly made up. An S orbital would almost never really hybridize with a P orbital (much less a D orbital). They are far to different in energy.
