# Quiz 6 Introduction to Quantum Theory

### Introduction to Quzntum Theory of the H Atom

• Wave and particle properties of electromagnetic radiation.
• Wave and particle duality of waves and particles.
• A brief history on the development of quantum theory.

### Electromagnetic Waves

• Describe the nature of electromagnetic radiation
• Give names for the various ranges of the electromagnetic radiation spectrum
• Give the range of wavelengths in the visible region
• Evaluate wavelength from frequency speed of light = 3.00e8 m s-1
= wavelength * frequency
in symbols commonly used
c = l n
• Evaluate frequency from wavelength
• Apply Planck's equation E = h n to evaluate energy of photon
• Apply Einstein's interpretation for the photoelectric experiment for problem solving.

### Magnetic Spectra

• spectra, absorption spectra, emission spectra, line spectra, continuous spectra
• hydrogen spectra, Raydberg equation, Raydberg constant,

### The Bohr Atom

• Bohr assumption
• Energy level of the hydrogen atom
• Transitions for light emission and absorption
• Balmer series

### Quantum Numbers and Atomic Orbitals

• Explain rules of quantum numbers.
• Apply quantum number rules to work out the atomic orbitals.
• Describe the properties of atomic orbitals.
• Give the shape of 1s, 2s, 3s, 2p, 3p, and 3d atomic orbitals.
• Describe Pauli exclusion principle.
• Describe Zeeman effect.

### Atomic Orbitals and the Period Table

• Describe the electron densities of various atomic orbitals.
• Plot the radial electron density for 1s, 2s, 3s, 2p, and 3d atomic orbitals.
• Construct the periodic table of elements from atomic orbitals.
