Here's what you should know:

  1. History of periodic table
  2. Names of groups
  3. Metals vs non-metals
  4. Periodic trends
    1. Ionization energy
    2. Electronegativity
    3. How reactive something is
  5. Be able to locate elements quickly on the table
    1. Name
    2. Atomic number
    3. Valence electrons
  6. Also, remember the following from last chapter.
    1. A = Z + N

Periodic Elements Lab

Today we did a lab involving different elements of the periodic table:

  1. Mostly metals
  2. Some nonmetals
  3. A metalloid
We looked at properties such as:
  1. Luster
  2. Density
  3. Malleability
  4. Atomic number
Homework:
  1. Finish lab report.  Double check that you have met all requirements.  Let's start the quarter strong.
  2. Finish element project

Arranging elements

In class we:

  1. Went over the exam
  2. Discussed various ways to arrange elements
This will lead into talking about the periodic table

Homework:

  1. Watch: Periodic Table
  2. Do: Periodic WSQ
  3. I really encourage you to watch it, but I understand if you don't get around to it.  My bad for not having it up sooner.

Unit 3 Exam

That's the last test of the quarter!  There will be time for corrections if you need it, but you've got to do it fast.  I'll need them by Friday afternoon.

Homework:
  No WSQ tonight.  I want to do some things in class without telling you all about our next chapter yet.  You might be able to figure it out (or remember) anyway.

Instead, I want you to pick your 10 favorite elements and look up five properties about each.  Please put this information in some sort of chart and put it in your Google Drive folder.

Atomic Mass

Today we talked about atomic mass:


  1. Z = protons
  2. N = neutrons
  3. A = mass number = protons + neutrons
  4. Atomic mass is an average of mass numbers
The test is next time.

Here are some things that you need to know:
  1. c = wavelength x frequency
  2. E = hf
  3. Electromagnetic spectrum
  4. Atomic models (Dalton, Thompson, Rutherford, Bohr, Electron cloud)
  5. Electron configurations
  6. Noble gas configuration
  7. Lewis Dot Structures
  8. A = Z + N
Please work some problems in the back of the chapter and come see me if you are confused about anything.

Homework:
  Study for exam

Electron Configurations

Mind blown?


  1. Orbital shapes
  2. Electron configurations two different ways
  3. Applied to periodic table

Here are a few links to what we were talking about in class about electrons being weird.

Dr. Quantum (youtube video)
Quantum Leap (NOVA Video)

Homework:
  1. Watch: Valence
  2. Do: WSQ - Valence
