I want to know how bonding electrons behave when they have to cover for both atoms. Electrons can spin around only one atom right? If so, then what happens when a covalent bond forms?
Let's say we have two covalent bonds between two atoms (for example: $\ce{C=O}$), so they have two pairs of shared electrons.
Since the double bond clearly exists, how do the electrons form the clouds that cover both atoms?
