Quantum Mechanical Model of the Atom

What is the Pauli Exclusion Principle?

• An atomic orbital can only hold a maximum of 2 electrons, each with opposite spins
• An atomic orbital can hold a minimum of 6 electrons, each with opposite spins
  
• An atomic orbital can hold a maximum of 6 electrons, each with the same spin
  
• An atomic orbital can hold a minimum of 2 electrons, each with opposite spins

What shape are P Orbitals? 

• Cloverleaf shaped
• Spherical shaped
• Hybrid structure

Hund’s rule states…

• Atomic orbitals have opposite spins and 2 electrons each
  
• Electrons occupy orbitals of highest energy first and energy level changes as you go up
  
• Electrons occupy orbitals of lowest energy first, starting with 1s
  
• Electrons occupy orbitals of equal energy, one electron enters EACH orbital ONE AT A TIME until orbitals of the entire energy level have one electron with the SAME SPIN.
