Due Monday 10/5
quantum mechanics review problems

1, 4, 5, 6, 7, 8, 9, 11
Due Friday, 9/25
section 4.3 electron orbitals Read entire section, answer question 1, 2, 3, 4, 5a, 5b on page 116.

chapter 4 reading guide

Here are some helpful links, please watch especially if you are having difficulty.
1. The orbitron. This website has visual representations of electron orbitals, it is the website I showed in class on Thursday.

2. Khan Academy: Introduction to the Atom. Two sets of videos describing the fundamentals of atoms. This covers material which was on the first test. If you still have difficulty with some of those concepts please watch these videos.
Khan: Introduction to the Atom

3. Khan Academy: Orbitals and Electrons. A set of 5 videos describing electron orbitals, electron configurations, and valence electrons.
Khan: Orbitals and Electrons

4. Atomic Orbitals. Another description of electron orbitals. This is similar to the reading I handed out. I give you the link because sometimes learning something from several different voices is helpful.
Atomic Orbitals

5. Another video describing quantum mechanics. The video is a bit beyond the scope of the class, however many of the required important concepts are discussed.

Due Thursday, 9/24
section 4.2 quantum model Read entire section. Answer question 1-3 on page 104.

The reality of electrons and light, weird stuff. Remember, It's the universe, not me. I'm just helping you to understand it.
  1. electromagnetic spectrum this video reinforces what you learned in section 4.1
  2. light as a wave and particle while this video specifies light, the same is true of electrons: they are also waves and particles.
  3. wave particle duality - OK, this video is your first introduction to the double slit experiment. It was a critical experiment which lead to some strange but important understandings of the quantum world. There are numerous videos which address this experiment and the results, so if you do not get it the first time around you'll get another chance. Yes, electrons behave differently if they are being watched!
  4. Brian Green explains double slit experiment view number 2. The results are all based on probability. If there is a 50% an electron will go through slit 1, and a 50% chance it will go through slit 2, then you can't tell which slit it goes through. Therefore it goes through both at the same time!
  5. double slit experiment explanation # 3
  6. Superposition ft. Schrodinger's Cat - Quantum Mechanics ep 2 - this video is the second part of the 3rd video on this list. It introduces the disturbing but accurate description of the quantum world know as Schrodinger's cat. This the same Schrodinger who created the wave equation which you will read about tomorrow.
  7. What can Schrödinger's cat teach us about quantum mechanics - Josh Samani - another video about schrodinger's cat thought experiemnet and an introduction to quantum entanglement.
  8. schrodinger's cat and superposition and parallel universes

This reading is due on Thursday. I'm posting it now because I recomend you read it twice, at a minimum.
