What is matter?

A) An object that take up space and has mass

B) The color of the object

C) The mixtures

Answer A

States of Matter

Solid Liquid 1. Has definite shape 1. Atoms move

alittle2. Has definite volume more freely3. Atoms are packed tightly 2. Water4.Particles vibrate 3. Atoms move 5. It is hard differently

depending on khjj temperature.

States of Matter Liquid4. Takes the shape of a container5. definite volume

Gas1.Takes up whole volume2. Particles get excited and move farther and farther 3. Definite shape4. cannot see a gas 5.carbon dioxide

Physical and Chemical PropertiesPhysical Properties- Is without changing the makeup

of a substance you can also observe or measure it. Examples: color, smell, freezing point, boiling point, and melting point.

Chemical Properties-Is when the properties of an object have a reaction. Examples: Hydrogen balloon, burning steel wool, alka seltzer, Zinc, Iodine reactions.

What is the difference between them? The difference between them is that physical you check

the shape, temperature,weight, etc.... With chemical you cannot observe checking the 5 senses .

Physical and Chemical ChangesPhysical Change- Is a change that does not

produce (make) a new substance. Example: stirring an egg, painting wood, cutting bread, water, glass breaking.

Chemical Change- Are changes that result in the productions of another substance. Example: burning paper, digesting food, baking a cake, fireworks, good car rusting.

What is the difference between them?Physical Change does not make a new

substance, but Chemical Change does .

Atom

What is an Atom?It is the smallest part of matter.An Atom has 3 different parts-Protron- positive charge-Electron- negative charge-Neutron- neutrally charged

Atom model

electrons (-) proton(+)

nucleus

neutron (O)

What is an Element?is a pure substance that cannot be broken down into

any simpler substances by chemical methods. Example: 1 2

carbon - element Dubnium - element 6 - atomic # 105 - atomic # C - symbol Db - symbol 12.o11 - atomic mass 262 - atomic

mass

Example: 3 4 Oxygen - element Nitrogen - element 8 - atomic # 7 - atomic # O - symbol N - symbol 15.999 - atomic mass 14.007 - atomic massExample: 5Aluminum - element 13 - atomic # Al - symbol26.982 - atomic mass

Compound

What is a Compound? A thing that is composed of 2 or more separated elements.Examples:Salt

Barite

Copper

Tin

Wood

Steel

Aluminum

Hematite

Plastic

Cotton

Periodic Table

What is a Periodic Table?-The periodic table is a table of the chemical elements in which

the elements are arranged by order of atomic number in such a way that the periodic properties of the elements are made clear.

How are they used? They are used to quickly locate information of that

certain element.

What is the pattern? The arrangement of all elements are in order to increase

atomic #.

Substance and Mixtures

Substance- A material with a definite chemical composition.

Mixtures- A material with a definite physical composition.

What is the difference between them? The difference between them is that with substance they

cannot be broken down physically, also a mixture cannot be broken do chemically.

Heterogeneous and Homogeneous

What is the difference between them?Heterogeneous and homogeneous refer to mixtures of

materials in chemistry. The difference between heterogeneous and homogeneous mixtures is the degree at which the materials are mixed together.

Heterogeneous Ex: Homogeneous Ex:- sand - blood- salt - glass of juice- tea - mixture of alcohol and water- soda - hard wine- milk - alcohol

Solutions

What is a Solution?A solution is a homogeneous mixture of one or more

solutes dissolved in a solvent.examples:- salt in water - tea - sugar in coffee- sugar in water - coffee

Solute- The substance that dissolves in a solvent to produce a homogeneous mixture

Solvent- The substance in which a solute dissolves to produce a homogeneous mixture

Examples

Solute examples- Solvent examples-

-chromium - salt

-iodine -water

-eggshells

-glue

-nail polish

Solubility

What does Solubility mean? The quantity of a particular substance that can dissolve in a

particular solvent.
