Unformatted text preview: -18 J n Heisenberg’s Uncertainty Principle-∆x × ∆mV ≥ h 4π Schrödinger’s Equation-ĤΨ = EΨ 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. Pauli’s Exclusion Principle- an orbital can house a maximum of two electrons and these two electrons must have opposite spin iii. Hund’s Rule – the most stable arrangement of electrons is that with the maximum number of unpaired electrons (electrons with the same spin)...
