1. What’s the Matter
foldable

2. Chemistry
Chemistry is the study of matter and the changes matter undergoes.

3. Matter
Matter is anything that takes up space and has mass.

4. General Properties
mass
weight
shape
volume
color
density
texture

5. Properties of Matter How It Looks (Shiny ,Dull, Color, etc.)
How It Feels (Hard, Soft, Rough , Smooth, etc.)
How It Smells (Sweet, Sharp, Terrible, No Smell, etc.)
How It Sounds (Loud, Soft, Echo, No Sound, etc.)
What It Does (Bounce, Stretch, Tear, Break, Magnetism etc.)

6. SOLIDS

7. Solids Characteristics definite shape definite volume
objects do not pass through easily
Examples: paperclip, bones, desk, car, chair, etc…

8. Solids
Molecules are very close
molecules move very slowly in place.

9. Liquids

10. Liquids Characteristics no definite shape definite volume
takes shape of container
has surface tension
example: water, soda, glue, oil, etc…

11. Liquids molecules have some space between them.
molecules move around a bit faster.

12. GAS

13. GAS Characteristics no definite shape no definite volume
expands to fill container
examples: oxygen, hydrogen, steam, air, carbon dioxide, etc…

14. GAS
Molecules have lots of space.
molecules very fast.

15. Metals Characteristics Most are solid at room temp. Except Mercury.
Most elements are metals
Located to the left of the zigzag line.
Shiny, conduct heat & electricity, and Malleable.

16. Non-Metals Located on the right side of the zigzag line.
Characteristics
Located on the right side of the zigzag line.
More then ½ are gases at room temperature.
dull, DO NOT conduct heat or electricity.

17. Metalloids Characteristics Border the zigzag line
Have properties of both metals and non-metals.
Called “semi-conductors”.

18. Compound
Molecule made of more then one type of atom, chemically combined in a fixed proportion.
CAN NOT be separated easily by physical means.
Properties of the compound are much different than the elements that make them up.

19. Sodium + Chlorine Na=Cl= NaCl
Compound
Example
Sodium + Chlorine Na=Cl= NaCl
greenish gas
Soft shiny metal
Salt

20. Mixture
Made up of different types of particles, they are NOT chemically combined.
tossed salad
CAN BE separated easily by physical means.
2 Types of mixtures
Homogeneous-the same appearance and composition throughout.

21. Mixtures
Heterogeneous-made up of different visible substances. Example oil and vinegar
Example;
Chocolate chip cookie recipe
Recipe ingredients+ baking=cookie

22. Molecules made up of only one type of atom
Element
Molecules made up of only one type of atom

23. Solutions Special Mixture where a substance dissolves in another.
particles are not big enough to be seen.
Particles spread out evenly
Example =
H2O

24. Physical Property
Characteristic of matter that can be seen through direct observation without changing the identity of the substance.

25. Density: mass/volume.
Brittleness: cracks/breaks.
Transparency: light passes through.
Boiling point: temperature liquid to gas.
Freezing point: temp from liquid to solid.
Melting Point: temp from solid to liquid.
Ductility: bends without breaking.
Elasticity: how much it can be stretched.

26. Physical Change
Change in which the identity of the substance does not change!
Atoms do not rearrange
only physical properties change, chemical do not change
No energy is produced.
Physical changes are generally easy to reverse.

27. Chemical Property
Characteristics of a substance indicating that it can change chemically. It changes one substance into another.

28. properties Flammability- ability to burn Combustible- explode
Rust- reacts with oxygen
React with Vinegar-produce new substance.
Oxidation- produces something new
All chemical changes include physical change

29. Chemical Change
How the particles of matter react with other kinds of matter and change.
color
temperature
bubble formation
can not be reversed
ex burning eggs

30. Chemical Change
Atoms are rearranged into different molecules
Both physical and chemical properties have changed.
Energy is often produced (heat)
CHANGES ARE NOT REVERSIBLE WITHOUT ANOTHER REACTION!
