Homework for Wednesday, October 1
chapter 5 - periodic law  read section 5.1

• This is a condensed telling of the periodic table story. How it was developed and it's significance. 
• On the unit test you do not need to know the names of particular scientists.
• Complete problems 3 and 4 on page 127

section 4.3 electron orbitals 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.
orbitron

2. Kahn 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.
Kahn: Introduction to the Atom

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

section 4.2 quantum model answer question 1-3 on page 104

chapter 4 reading guide

Sorry, this is wierd stuff and I am sick thus I can not help you make sense of it today, hopefully tomorrow.

VIDEOS - given the difficulty of this subject I chose to delay the next reading for a day so I can explain some things for you. In the mean time I thought it would be helpful for you to watch some videos. Please watch them all. There are repeat concepts but multiple viewings of these abstract concepts should help. There is about 50 minutes of video here so be efficient with your time.

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.
