"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. " - How do electrons dictate how elements behave
