Take out the following:Pencil Planner (p. 84)HighlighterChemistry Workbook page 17
Elements, Compounds, and Mixtures
Matter
Pure Substance Mixture
(leave blank for now)Element Compound
Copy this graphic organizer into your workbook on page 17.
This should take up the entire page. You will be adding notes to each box.
Matter
Anything that has mass or takes up space.
Pure Substance
• Made ONLY of elements!• Cannot be separated physically– Water– Sugar– Aluminum– Salt
Textbook pages 38-41
• Read pages 38-41 • DO NOT READ Heterogeneous or
Homogenous Mixtures on page 41• Fill in the boxes on your graphic
organizer–Definition–2 facts–2 examples
Notes
• As I go through these notes–Highlight any information you
have that is the same–Add any information you don’t
have and highlight.
Element
• Made of one type of atom.• Cannot be broken down into a simpler
substance
Compound• Two or more elements chemically combined.
(forms a new substance)• Can only be separated by a chemical reaction.
(chemical bonds get broken)• Examples:
H2O HCl (hydrochloric acid) C6H12O6
(sugar)
Mixture
• Can be made of elements and/or other non-pure substances.
• Physically combined • Can only be physically separated– Examples: melted together, mixed together in
container• No new substance is formed
Solution
• Type of mixture• All substances evenly distributed• Examples: sugar water, salt water,
bronze (copper and zinc are melted together)
Identify the following examples…You will be shown a series of photos. Tell if each photo
represents an item composed of an element, compound, mixture, or solution.
Review:• An element contains just one type of atom. • A compound contains two or more different atoms
joined together. • A mixture contains two or more different substances
that are only physically joined together, not chemically.• A solution is a mixture where all the substances are
mixed together evenly.

Match each diagram with its correct description. Diagrams will be used once. For each number write the name (For example: Pure Element) and draw the picture that matches. You do not have to write the definition.
Let’s Review!
Check your answers
1. ___Pail of Garbage2. ___A dog 3. ___Ammonia (NH3)
4. ___Kool-aid5. ___Salt (NaCl)6. ___Energy7. ___Gold (Au)
8. ___Pizza9. ___Dry Ice (CO2)
10. ___Baking Soda (NaHCO3)
11. ___Titanium (Ti)12. ___Iced Tea
Classify each of the following as elements (E), compounds (C), mixtures (M), or solutions (S). Write the letter X if it is none of these.
