Quantum Mechanical Model of an Atom

What is the shape of p orbitals?

• Peanut shaped

• Spherical shaped

• Flower shaped

• Dumbbell shaped

How many electrons can the first energy level hold?

• 1
• 2
• 8
• 0

What is the maximum number of electrons that can be on the p sublevel?

• 6
• 3
• 2
• 4

What shape are d orbitals?

• Peanut shaped

• Spherical shaped

• Dumbbell shaped

• Clove leaf shaped

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 there in the "d" sublevel?

• 1
• 3
• 5
• 7

How many orbitals are there in the "s" sublevel?

• 1
• 3
• 5
• 7

Which sublevel has the highest energy?

• 3s
• 3d
