WebOne way to visualize delocalization is that electrons flow through the orbitals of adjacent atoms. These electrons can be non-bonding (lone pairs) or bonding electrons. More specifically they must be either non-bonding or π bond electrons. When the electrons in π bonds are capable of flowing through the orbitals of adjacent atoms, they are ... WebDefinition. 1 / 2. All electrons surrounding an atom maybe classified as belonging to a bonding or nonbonding pair of electrons. A non-bonding pair only revolves around the one atom while a bonding pair revolves around the two atoms sharing the electrons.
