What does the QMM determine? The energies an electron may have and the various locations around the nucleus.
How do two sublevels of the same energy level are different from each other? Each sublevel represent an orbital of different shape.
How can electrons in an atom move from one energy level to another? An electron must gain or lose the right amount of energy.
Quantized electrons The amount of energy an electron took to move from one energy level to another.
