Rules of Electron Configuration Basics

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
