Liz LaRosa updated 2015 1

2. Outcomes and Criteria 7M5
Interpret simple models that represent elements, mixtures and compounds.
E Level
Identify simple elements, mixtures and compounds.
D Level
Identify elements, mixtures and compounds from given representative models.
M Level
Interpret and explain why given models represent elements, compounds or mixtures.

3. Elements Atoms Molecules Compounds
Pure Substances
A sample of matter that has definite physical and chemical properties.
Elements
Atoms
Molecules
Compounds

4. Elements
Pure substances that cannot be separated into simpler substances by physical or chemical means.

5. Compounds
Pure substances composed of two or more different elements joined by chemical bonds.
Made of elements in a specific ratio that is always the same.
CO2
Has a chemical formula.
Can only be separated by chemical means not physical .
H2O
NaCl

6. Mixtures
A combination of two or more pure substances that are not chemically combined.
Substances held together by physical forces, not chemical.
No chemical change takes place.
Each item retains its own properties in the mixture.
They can be separated physically.

7. What Do You Think? Is it ……. Compound
An element contains just one type of atom.
A compound contains two or more types of atom joined together.
A mixture contains two or more different substances that are only physically joined together, not chemically.
Compound

8. What Do You Think? Is it ……. Element
An element contains just one type of atom.
A compound contains two or more types of atom joined together.
A mixture contains two or more different substances that are only physically joined together, not chemically.
