Unformatted text preview: -18 J n Heisenbergs Uncertainty Principle-x mV h 4 Schrdingers Equation- = E Quantum Numbers: The total number of orbitals possible for each value of n is n 2 The number of different subshell types with in a shell equals to n The number of orbitals within a subshell equals 2l + 1 The number of nodes is n-1 Rules for occupying orbitals in many-electron atoms: i. Building up principle- occupy subshell with lower energy first and fully before occupying subshell with higher energy. ii. Paulis Exclusion Principle- an orbital can house a maximum of two electrons and these two electrons must have opposite spin iii. Hunds Rule the most stable arrangement of electrons is that with the maximum number of unpaired electrons (electrons with the same spin)...
