What are atoms, elements, molecules, and compounds?
SPS2: Students will explore the nature of matter.
Draw the picture below in your notes:
– Write and answer the following:
1.What are the atom(s)?
2.What are the elements?
3.What is the molecule?
Chemistry – study of matter and how it behaves
Classification of Matter• Atom
• Element
• Molecule
• Compound
Atom – smallest piece of matter• 110+ different kinds of
atoms• Combine to make all
the forms of matter in universe
• Too small to see but can see with the most POWERFUL microscopes
The Atom
Part Charge
Electron Negative (-)
Proton Positive (+)
Neutron None (X)
Element – a pure substance• Groups of all the same kind of atoms
Molecule – two or more atoms joined together
Diatomic Molecules – two of the same atoms
H2
Cl2
O2
Compound – groups of the same kind of molecules
An Overview of the LINCS Strategy
Step 1: List the parts
Step 2: Identify a Reminding Word
Step 3: Note a LINCing Story
Step 4: Create a LINCing Picture
Step 5: Self-test
Creating LINCS Table
Keep in mind:
• That you must go in order
•Box 1
•Box 2
•Box 3
•Box 4
•Box 5

element
Box 1.
Write the word to be learned on the top half. Then circle it.
Creating LINCS Table
A pure substance. element
Box 2.
Write the parts of the definition you need to remember.
Underline key terms.

A pure substance.element
Box 3.
Write the Reminding Word.
elephant
Creating LINCS Table
The elephant pooped a pure substance
A pure substance.element
Box 4.
Write the LINCing Story.
Using the reminding word (Box 3) and the key words from definition (Box 2).

Box 5.
Draw the LINCing Picture.
Picture should reflect the LINCing story (Box 4).

TOD
• Create a colored poster of one of your LINX tables.
• We will share at the end of class.
Activator
• What do the prefixes mean:
–Homo
–Hetero
Mixture – combination of materials• Not chemically
joined
• Can be separated physically– Sorted, filtered,
evaporation
2 kinds of mixtures• Homogenous – same
throughout – Ex: tea, kool-aid, air
• Heterogeneous – not the same throughout
ex: salad, salt&pepper
Homogeneous mixture – same
Heterogeneous – not same
TODColumn A Column B
1. Summer Sausage
2. Steam
3. Salt Water
4. Pencil lead (Pb)
5. Dirt
6. Pepsi
7. Silver (Ag)
8. Toothpaste (Na2HPO4)
9. A burrito
10. Italian Dressing
11. Chicken Soup
12. Lemonade
Column A lists a substance. In Column B, list whether the substance is an element (E), a compound (C), a Heterogeneous Mixture (HM), or a Solution (S). (Remember a solution is a homogeneous mixture.)
