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

element

Box 1.

Write the word to be learned on the top half. Then circle it.

A pure substance. element

Box 2.

Write the parts of the definition you need to remember.

Underline key terms.

Box 3.

Write the Reminding Word.

Box 4.

Write the LINCing Story.

Using the reminding word (Box 3) and the key words from definition (Box 2).

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.)
