WebThe best definition of valance electrons in general are the electrons that participate in chemical reactions. For transition metals that means d orbitals and a higher s orbital. So for a transition metal in the fourth period like copper, Cu, this would mean a 4s and 3d orbital. WebElectrons move around in "quantized" energy states. Meaning they exist in a specific energy state, and can be anywhere at any given time in that orbital due to the heisenberg uncertainty principle. Think of "quantized" as the smallest units of energy states a particle can have.
