Unformatted text preview: e, they must be repelling, so at least the spin quantum number is different! least The Pauli Exclusion Principle says that no two The Pauli electrons within an atom (or ion) can have the same four quantum numbers. same If two electrons are in the same energy level, If the same sublevel, and the same orbital, they must repel. must Think of the 4 quantum numbers as the address Think of an electron… Country > State > City > Street Street 26 Energy Levels • Each energy level has a number Each called the PRINCIPAL called QUANTUM NUMBER, n QUANTUM • Currently n can be 1 thru 7, Currently because there are 7 periods on the periodic table the 27 Energy Levels n=1 n=2 n=3 n=4 Relative sizes of the spherical 1s, 2s, and 3s orbitals of hydrogen. 28 29 Types of Orbitals • The most probable area to find The these electrons takes on a shape these • So far, we have 4 shapes.
