Task 2: Reading the Periodic Table
Atoms are just ONE unit of an element. A bar of gold (an element) might have quadrillions of atoms in it.
The periodic table organizes all of the atoms/elements in a table based on properties and atomic structure. We can read the chart to learn facts about the elements - the number of protons, the number of neutrons, the atomic weight, the atomic mass, and the number of electrons in a neutral atom of that element.
1) Copy this diagram onto the top of page 29.
2) Copy down the following rules for reading the periodic table: Atomic number = Number of protons Mass number = Atomic Weight rounded to nearest number Number of neutrons = Mass - Protons Electrons = usually the same as protons
3) To practice this with a visual model, try out the "Atom Builder" at this site (you'll need to set your security for apps to "anywhere") Atom Builder
Make sure you keep your atom's charge at 0 and keep the atom stable. You should be able to see a visual connection between the information in the box in the periodic table and the atom you build.
Task 3: Practice "Numbering Atoms"
Use the numbering atoms worksheet to practice reading the periodic table to determine the atomic number, number of protons, number of neutrons, and the number of electrons.
HINT: If you get stuck, check out this website: http://education.jlab.org/qa/pen_number.html
Closure:
Quiz yourself - pick another atom from the periodic table. Figure out from the table its atomic number, number of protons, number of neutrons, and the number of electrons
HOMEWORK: Study for the phase change quiz (and make sure you've completed your lab report) - you need to know:
- the definitions for evaporation, melting, freezing, condensation, sublimation, and deposition are.
- what phase changes involve a gain in thermal energy or a loss of thermal energy
- how to draw and label a heating curve graph
- how to read a heating and cooling curve graph and figure out what is happening
The quiz is Thursday for period 6, Friday for period 3, and Monday for period 5!!!

5) Set up your page so there are 8 boxes
6) Go on to task 3 when you've finished setting up your page
Task 3:
1) Read this:
You may have noticed while using the "Atom Builder" interactive simulation that it organized the atom with the nucleus at the center and the electrons in rings around it. See below:
Do you see how there are two electrons in the first ring and then more electrons in the second ring? When we organize an atom diagram like this, it is called a Bohr diagram or a Bohr model. It is not the most accurate model of an atom, but it works well for getting a basic understanding of how electrons are organized at different levels in an atom and - in 8th grade - why atoms lose or gain certain amounts of electrons to become stable. (Look up electron orbital shapes in google images if you are curious to see a college-level model.)
