The next table is called the Energy Matrix Table. It is arranged according to the electron filling patterns of the atoms of each element. The Four Quantum Numbers are given in the table. The Principal Quantum Number, “N” appears at the top of each level. The Quantum Numbers “L” is indicated by the different colors. The Magnetic Quantum Number, “M” appears next to the element that has those levels. Spin Quantum Number “S” is determined by dividing each panel in half horizontally.
