lesson 1

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

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

• 6
• 3
• 2
• 4

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.
  

There are 4 different types of sublevels: s,p,d,f
