Periodic Table Week 2 Day 4 Friday – Learning Log, Quiz, Periodic Table
DSJ (11-6-15) Learning Log Periodic Table
1. Take out your DSJ. Read last week’s Learning Log (11-6-15) Notice any corrections your teacher made.
2. Use the following heading for today’s DSJ
Title: “Learning Log on Periodic Table: Periodic Table Organization
Upper Left Hand Corner Heading (Name, Date, Period)
1. Draw Periodic Square and a Bohr model of the atom your teacher assigns you to.
2. Claim: The periodic table is organized. (Write this claim down)
3. How is the periodic table organized? Include in your opening statements how the periodic table was
organized ORIGINALLY by Mendeleev (you know the answer) . What information can you obtain from a
periodic square? Make sure to include what you know about the periodic table based on the location of
each periodic square within the table. Explain how all of this information is important to building a Bohr
Model of the Atom. You should include what you know about the reactivity of an element based on the
Bohr Model and placement of an element within the Periodic Table also.
Terms you should include, but are not limited to are:
a. Atomic Number and Atomic Mass, Valence Electrons, REGIONS: Metals, Non-Metals, Metalloids;
Columns/Groups/Families: Noble Gases, Alkali Metals, Alkaline Earth Metals, and Halogens. Explain
Bohr Model, Periodic Square, Zig-Zag Line, Rows/Periods.
b. Must be complete sentences.
c. Highlight and number your periods.
d. Stack your DSJ (opened to the Learning Log) on the corner of the desk.
ECQ Quiz (10 Minutes)
HOMEWORK
Text Notes:
IP 55 Ions p. 204-205
A. How does an ion form?
B. How are ions written so you can recognize them in text?
C. What groups of elements are likely to lose electrons?
D. What groups of elements are likely to gain electrons?
Remember
1. Atoms like Full Outer Shells (Like the Noble Gases)
2. Atoms are Lazy (Just like 8th graders).
3. It takes no more Energy to gain or lose the same number of Electrons
E. 4. The net charge is the difference between the Number of Protons (Atomic Number) and the total number of
remaining electrons after losing/gaining them.
a. If you lose an electron, it is like SUBTRACTING A NEGATIVE (net charge will be positive)
b. If you gain an electron, it is like ADDING A NEGATIVE (net charge will be negative)
c. I hope you were paying attention in 7th grade Math!!!
F. Special Rules: Hydrogen can gain or lose an electron to fill its outer shell because hydrogen has half of a full
outer shell.
