Quantum Theory – Skillz

• Calculate the wavelength of electromagnetic radiation given its frequency or its frequency given its wavelength.
• Explain what photons are and be able to calculate their energies given either their frequency or wavelength.
• Explain how line spectra relate to the idea of quantized energy states of electrons in atoms.
• Explain how the uncertainty principle limits how precisely we can specify the position and the momentum of subatomic particles such as
  electrons.
• Relate the quantum numbers to the number and type of orbitals and recognize the different orbital shapes.
• Draw an energy-level diagram for the orbitals in a many-electron atom and describe how electrons populate the orbitals in the ground state
  of an atom, using the Pauli exclusion principle and Hund’s rule.
• Use the periodic table to write condensed electron configurations and determine the number of unpaired electrons in an atom. (Section 6.9)Homework

• 18, 23, 28, 37, 56, 70 (full + orbital diagrams)

Homework

• Complete the work for homework (on paper)
• Note – show supporting work for all questions
