Quantum Model & E- Configuration

What is the shape of s orbitals?

• Dumbbell shaped

• Peanut shaped

• Spherical shaped

• Hybrid structure

How many electrons can the first energy level hold?

• 1
• 2
• 8
• 0

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.
  

How many orbitals are in each sublevel?

• s:1 p:3 d:5 f:7

• s:2 p:6 d:10 f:14

• s:1 p:6 d:5 f:14

• s:2 p:3 d:10 f:7
