1. Elements, Compounds & Mixtures Created By Mr. Vitale

2. Matter Matter is what makes up all of the STUFF around us.
Matter is anything that has mass and takes up space
Examples- Cars, Pizza, I-phones, Football Players, trees, water, gold, etc.
Matter can be made up of one type of material or a mixture of many.

3. Pure Substances
A pure substance is something that has definite properties (characteristics)
There are 2 types of pure substances:
1) Elements 2) Compounds
Some of these are physical properties: appearance, melting point, electrical conductivity
Some of these are chemical properties: reactivity, flammability, the ability to rust, etc.

4. Elements
An element is a pure substance (only 1 type of particle) that cannot be separated into simpler substances by physical or chemical means.
Listed on the Periodic Table.

5. Element

6. The periodic table list all of the elements known to scientists.
True
False

7. Elements are considered to be a “pure substance”
True
False

8. Which of the following is NOT an example of an element?
Oxygen (O)
Argon (Ar)
Salt (NaCl)
Silver (Ag)
[Default]
[MC Any]
[MC All]

9. Compounds
A compound is a pure substance composed of 2 or more elements that are chemically combined
Scientists call this a Chemical Bond

10. Hydrogen (H) + Oxygen (O)
Examples of Compounds
Compounds contain elements
The elements combine + lose their original properties
Compounds CAN be separated by chemical means
By looking at the number that follows each symbol you can tell how many atoms each compound has.
Sodium (Na) +
Chlorine (Cl)
NaCl
Hydrogen (H) + Oxygen (O)
H2O
Carbon (C) + Oxygen (O)
CO2

11. You can often identify compounds because they will have multiple symbols listed after them like: H2O CO2 NaCl Al2O3
True
False

12. Which of the following is an example of a Compound
A gold and silver necklace
Salt (NaCl)
Milk
Air
[Default]
[MC Any]
[MC All]

13. How many atoms of Oxygen are in Carbon Dioxide (CO2)1 2 3
None
[Default]
[MC Any]
[MC All]

14. Mixtures
A mixture is a combination of 2 or more substances that are not chemically combined.

15. Examples of Mixtures Properties of Mixtures:
chicken noodle soup
salad
pizza – yes, that would be Yoda…
Properties of Mixtures:
Each substance in a mixture keeps its identity
You can physically separate them
They also contain elements, compounds, or both
And they can be formed using any ratio of
components

16. Mixtures may be homogeneous or heterogeneous
The prefix “homo” indicates the same
Homogeneous mixtures have the same appearance and properties throughout the mixture
The prefix “hetero” indicates difference
Heterogeneous mixtures consist of visibly different substances

17. Examples of Homogenous Mixtures
Milk
Salt Water
Koolaid
Soda

18. Examples of Heterogeneous Mixtures
Italian Salad Dressing Chicken Noodle Soup Pizza Jello with Fruit in it

19. Salt water is an example of a…
Homogenous Mixture because it looks the same throughout.
Homogenous Mixture because it has Salt (NaCl) in it.
Heterogenous Mixture because it looks the same throughout.
Heterogenous Mixture because it has chunks floating around it it

[MC Any]
[MC All]

20. Which of the following is an example of a heterogeneous mixture?
Chocolate Milk
Sprite
Salt Water
Sprite with ice cubes
[Default]
[MC Any]
[MC All]

21. There are THREE types of mixtures:
Solutions
Suspensions
Colloids

22. Solutions
A solution is a mixture that appears to be a single substance, but it is actually composed of 2 or more substances that are distributed evenly amongst each other.
SOLUTIONS ARE HOMOGENEOUS
sugar & Kool-Aid powder are dissolved in water
carbon dioxide is
dissolved in water
salt is dissolved in water

23. Suspensions
A suspension is a mixture in which particles of a material are dispersed throughout a liquid or gas, but are large enough that they settle out.
SUSPENSIONS ARE HETEROGENEOUS
That water is disgusting!
muddy water
Italian dressing

24. Which of the following is an example of a solution?
A heterogeneous mixture that has chunks floating in it.
A heterogeneous mixture that has been blended until smooth.
A homogeneous mixture that has salt dissolved in it
None of the above.

25. Which of the following is NOT an example of a suspension?
Dirt mixed with water
Italian Salad Dressing
Coke with Ice Cubes
Orange Gatorade
[Default]
[MC Any]
[MC All]

26. Colloids
A colloid is a mixture in which the particles are dispersed throughout but are not heavy enough to settle out.
COLLOIDS ARE HOMOGENEOUS
Colloids have properties of both solutions & suspensions.
mayonnaise
milk

Table salt
Salad
Mayonnaise
Italian dressing
Pepsi
Oxygen
Hydrogen
