Electron Configuration and Ionic Bonding Review

How many electrons can the first energy level hold?

• 1
• 2
• 8
• 0

Which of the following statements is true about the 3s and the 4s sublevels?

• These sublevels have the same energy
• These sublevels are the same distance from the nucleus
• These sublevels hold different amounts of electrons
• These sublevels have the same shape

Electrons occupy orbitals of lowest energy first is part of what electron configuration rule?

• Hund’s Rule
• Aufbau Principle
  
• Pauli Exclusion Principle

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.
  

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
