Electron Configuration

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

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
  
• Fill orbitals of the same energy with one electron, then go back and pair them up if you have extra electrons
