Where is the Electron Located?
The Quantum Model of the Atom Heisenberg uncertainty principle: It is impossible to determine both the position and velocity of an electron or any other particle
What is the Address of the Electron? Principle Quantum Number (n): Indicates the energy level occupied by an electron. Angular Momentum (l): Indicates the shape of the orbital (s,p,d,f,g)
Atomic Numbers and Quantum Numbers Magnetic Quantum Number (m): Indicates the orientation of an orbital around the nucleus. Spin Quantum Number (): Indicates which way the electron is spinning
What are the Rules Governing Electron Configuration? Aufbau Principle: An electron occupies the lowest energy orbital available Pauli Exclusion Principle: Only two electrons per orbital and they must spin in opposite directions Hunds Rule: Each orbital of equal energy must have one electron before a second electron is added
Lets Fill Up The Orbitals!
