Close up view of atoms and their behavior

•Changing from one state to another is a Physical Change.

•If a new substance is formed it is a Chemical Change.

• The building blocks of Matter• Consists of Protons (+), Electrons (-), and Neutrons (N).

• Consists of only one kind of atom, • Cannot be broken down into a simpler type of matter by either physical or chemical means• Can exist as either atoms or molecules.

• A molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together. • In the animation above, two nitrogen atoms (N + N = N2) make one Nitrogen molecule .

Animated images and notes from http://www.chem.purdue.edu/gchelp/atoms/elements.html

• Atoms of two or more different elements bound together.

• Can be separated into elements chemically, but not physically.

In the animation above, water (H20) is a compound made of Hydrogen and Oxygen.

• Solutions are groups of molecules that are mixed up in a completely even distribution.

• Uniform Distribution.• Example: Sugar and Water

• The substance to be dissolved.

• The one doing the dissolving.

• Particle sizes are in between the size of particles found in solutions and suspensions .

• Can be mixed and remain evenly distributed without settling out.

• They are substances held together by physical forces, not chemical.

• Can be separated physically.

• Solutions are also mixtures.

• The substances are not uniformly mixed.

• Example: Sand in a glass of water.Images are from http://www.chem4kids.com

• Are heterogeneous mixtures consisting of parts that are visible to the naked eye.

Example: the ingredients in salad dressing

• Substances will settle over time.

What is matter?What is matter?

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

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.)

SOLIDSSOLIDS

SOLID

A solid is matter that has that has definite size and shape.

Example: Put a sneaker in a box. It stays the same.

LiquidsLiquids

LIQUIDA liquid takes the shape of any container.

Example: Pour juice into a glass. The juice will take on the shape of the glass.

GASGAS

Gas

Gas is matter that has no definite shape. Gases take the shape of whatever container they are in .

Example: The air all around us is a gas.

Physical changes in matter

A Physical change is a change in how matter looks, but not the kind of matter is it is.
