Chemistry – study of matter and how it behaves
![Page 4: What are atoms, elements, molecules, and compounds? SPS2: Students will explore the nature of matter](https://reader035.vdocument.in/reader035/viewer/2022062321/56649ed35503460f94be2993/html5/thumbnails/4.jpg)
Classification of Matter• Atom
• Element
• Molecule
• Compound
![Page 5: What are atoms, elements, molecules, and compounds? SPS2: Students will explore the nature of matter](https://reader035.vdocument.in/reader035/viewer/2022062321/56649ed35503460f94be2993/html5/thumbnails/5.jpg)
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
![Page 8: What are atoms, elements, molecules, and compounds? SPS2: Students will explore the nature of matter](https://reader035.vdocument.in/reader035/viewer/2022062321/56649ed35503460f94be2993/html5/thumbnails/8.jpg)
Molecule – two or more atoms joined together
Diatomic Molecules – two of the same atoms
H2
Cl2
O2

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

TOD
• Create a colored poster of one of your LINX tables.
• We will share at the end of class.

• What do the prefixes mean:
–Homo
–Hetero

Mixture – combination of materials• Not chemically
joined
• Can be separated physically– Sorted, filtered,
evaporation
![Page 21: What are atoms, elements, molecules, and compounds? SPS2: Students will explore the nature of matter](https://reader035.vdocument.in/reader035/viewer/2022062321/56649ed35503460f94be2993/html5/thumbnails/21.jpg)
2 kinds of mixtures• Homogenous – same
throughout – Ex: tea, kool-aid, air
• Heterogeneous – not the same throughout
ex: salad, salt&pepper
