2. What is Chemistry?
The study of the , , and of matter and the it undergoes.
Chemistry is a science.
A basic understanding of chemistry is to all other sciences.
Chemistry is also central to our

3. Branches of Chemistry
Organic Chemistry - study of all substances containing
Biochemistry- study of the chemistry of
Physical Chemistry – study of theories and experiments that describe the of substances

4. Branches of Chemistry
Analytical Chemistry – study of the of substances.
Inorganic Chemistry - study of substances carbon
Theoretical Chemistry – using to understand principles, design and predict properties of substances

5. What is Matter? Matter is anything that takes up and has .
is a measure of the amount of matter.
is the force of gravity on mass.

6. Classifying Matter by Composition
– matter with a uniform composition
- matter without a uniform composition
- A pure type of matter that does not vary from sample to sample. Includes and

7. Classifying Matter by Composition
Elements- simplest kind of matter, made of one type of .
An atom is the smallest unit of an element that maintains the of that element.
Elements cannot be broken down into simpler substances by ordinary means
List Examples:

8. Classifying Matter by Composition
Compounds – matter composed the atoms of two or more elements that are bonded.
Compounds can be broken down by methods
When they are broken down, the components have completely properties than the compound.
List Examples:

9. Classifying Matter by Composition
A is a blend of two or more kinds of matter, each of which retains its own identity and properties.
A mixture is mixed together .
Variable composition, often expressed by a by mass or volume
Homogeneous mixtures are also called . List Examples:

10. Mixtures A mixture is not the same throughout (not uniform).
List Examples:

13. States of matter
Solid- matter that can not flow and has volume and shape
Liquid- definite volume but no definite
- a substance without definite volume or shape and can flow.
Plasma- a substance that is similar to a gas, but loses due to its high temperature

14. States of Matter (Copy on separate paper)
Definite Volume
Definite Shape
Particle position and movement
Solid
Liquid
Gas

15. Properties of Matter
Property- a property that can be observed and measured without changing the identity of the substance.
List Examples:
Property-relates to a substance’s ability to undergo changes that transform it into different substances.

16. Properties of Matter
Chemists use properties to and matter. More than one property must be used for identification.
Properties – do not depend on the amount of matter present
List Examples:
Properties – depend on the amount of matter present

17. Changes in Matter
A change does not change the composition or identity of the substance.
List Examples:
Boiled water is still .
All are physical changes

19. Changes in Matter
– a process in which a solid changes directly to a gas without going through a liquid phase.
List Examples:

20. Changes in Matter
A change occurs when one or more substances are changed into new substances.
Reactants- substances that react
Products- substances that form
Products have

21. Indications of chemical change
1.)  Production of , , , .
2.) Production of a
3.) Formation of a
4.) A change in
5.) A change in

22. Separating Mixtures Mixtures are separated by their .
Primary methods of separating mixtures are:

23. Separating Mixtures
Filtration is a method used to separate the components of mixtures that contain an solid and a liquid. List Example:

24. Separating Mixtures
Distillation is a method of separating substances in a mixture by of a liquid and subsequent of its vapor.
List Example:

25. Separating Mixtures Centrifuge
Used to separate / mixtures such as those in blood. The centrifuge spins rapidly and causes the solid precipitate to settle to the bottom.
List Example:

26. Separating Mixtures
Chromatography is a method of separating mixtures that uses a phase and a phase. chromatography can be used to separate dyes and pigments because they move at different rates on the paper.

27. Elements There are naturally occurring elements
Each has a 1 or two letter .
First letter always second letter is .

28. Elements The periodic table shows the elements organized by their
Columns on the table represent or of elements with similar chemical properties
Properties vary across the horizontal rows or

29. Elements
Three general classes of elements are , , are on the left and in the center of the periodic table. are on the right. are on the zig-zag dividing line.

Metalloids have properties
Metalloids are

37. Elements
(Group 18) are nonmetals that are essentially non-reactive elements. They are gases at room temperature
