FAQ: What do I need to
write in my notebook?
 Bold words need to be
copied exactly.
Italics gives instructions
or useful information.
This only needs to be
copied if it is bold.
Elements and Their Properties
What: Identify elements
How: Elements and Their Properties Lab
Why: Get familiar with periodic table.
Please continue to read and follow all directions.
Launch: Silicon vs. Lead
1. Silicon looks different than lead because . . .
2. An atom of silicon is different than an atom of lead
because . . .
Class Discussion: Chemistry Unit Introduction
 Why is a carbon atom different than a sodium atom?
 In general, what makes atoms of two elements different?
 Let’s make a list of our thoughts and ideas.
Chemistry: The study of matter, of the properties of elements,
and how atoms react and combine.
Skill Practice: Elements and Their Properties
Examine each element substance. Make observations and
complete the table.
Note: “HCl” stands for Hydrochloric Acid.

Personal Periodic Table
What: Read the periodic table
How: Make Personal Periodic Table
Why: Spot numbers that identify an element
Please continue to read and follow all directions.
Launch: Please collect a pretest on reading a square on the
periodic table. Complete the pretest to the best of your ability.
You are not being graded on this, so don’t stress.
Research: Periodic Numbers {Use your cell phone or a computer.}
Define the following terms:
Atom:
Proton:
Electron:
Neutron:
Atomic Number:
Atomic Mass:
Skill Practice: Personal Periodic Table
- Research the squares on the periodic table and write into
your own personal periodic table. (Periodic Table Basics)
- Use Chem4Kids.com to find all the relevent information.
 Go to Element List, choose element, “More about orbitals
and compounds.”
 Bohr Diagram is located at the end of More about orbitals
page. (If you want, you can search Lewis dot structure.)
Note: We will work on more understanding over this unit.
Exit Ticket:

Neutrons
What: Identify differences in atoms
How: Calculate neutrons, atomic worksheet
Why: Use elements to study matter.
Please continue to read and follow all directions.
Launch: The number of protons in:
a. Carbon:
b. Sodium:
c. Magnesium:
d. Lead:
I know this because . . .
Class Discussion: Calculating Neutrons
- Reminder: Protons determine the type of atom.
- Number of neutrons in an atom varies. This is called an
isotope.
- Mass Number = # of protons + # of neutrons.
{See YouTube Videos or Week 21 on Schulze TeacherPage.}
Skill Practice: Atomic Worksheet2
- Complete the worksheet based on the periodic table.
- # of protons = Atomic Number
- # of electrons = # of protons (this is a neutral atom.)
- Mass number = # of protons + # of neutrons
- # of neutrons = mass number - # of protons
(Mass number must be a whole number!!!! You can’t have
half a neutron. Use atomic mass and round up.)
Exit Ticket: The number of neutrons in Tin-120 are . . .
(Note: Tin has the symbol Sn.)

Aluminum vs. Sulfur
What: Explain differences in atoms
How: Write to Explain: Sulfur vs. Aluminum
Why: Foundation of chemistry
Please continue to read and follow all directions.
Launch: Comparing two elements.
Note: The dots on the circles are electrons!
1. The two atoms are the same because . . .
2. The two atoms are different because . . .
Class Discussion: Claim/Evidence/Explanation
 Claim: Are sulfur and aluminum different? How?
 Evidence: Which physical properties of sulfur and aluminum
are different?
 Explanation: How are atoms of sulfur and aluminum
different?
Skill Practice: Writing to Explain.

Launch: Writing to Explain – Element Comparisons
- We started the week by making observations of different
pure elements.
- These observations, we can see that elements are different.
- In the “Support claim with evidence” section, discuss the
different physical and chemical properties.
- In the “Possible Scientific Explanation”, talk about the
different properties of atoms.
- You may use other data for top marks.
Skill Practice: Worksheet
- Complete “A World Famous Table” worksheet (both sides)
and turn in.
