They are hydrogen, nitrogen, oxygen, fluorine,chlorine, bromine, iodine and astatine.
They are diatomic because they have to exist in pairs. They are called diatomic and not compounds because they cannot be chemically broken.

Matter is anything that is mass and takes of space.
Mass-  a large body of matter with no definite shape.
Volume- the amount of space that a substance or object occupies, or that is enclosed within a container.
-Mass divided by volume gives you density

# data[].attributes.body
Gas- an airlike fluid substance which expands freely to fill any space available, irrespective of its quantity.
Vapor- a substance diffused or suspended in the air, especially one normally liquid or solid.

# data[].attributes.body
Matter is rather a pure substance or a mixture.
A pure substance cannot be physically separated. A pure substance can be broken down into two parts.
Element and Compound:
Element- the simplest form of a pure substance. It cannot be physically or chemically broken down
Compound- pure substances that are made of two or more elements. It cannot be CHEMICALLY broken down. It is always a fixed composition.

# data[].attributes.body
A mixture has two or more substances. It is not chemically combines, can be physically separated, and it can retain individual properties. A mixture can be rather a heterogeneous mixture or a homogeneous mixture.
Hetero- (Different) Is not evenly distributed and not uniformed. Examples: Trail mix, fruit jello
Homo- (Same) Evenly distributed  and is uniformed.
Solution- Is a special kind of mixture. a solution is when one mixture dissolves into another

# data[].attributes.body
Solution- is always transparent, light passes through with no scattering from solute particles
which are molecule in size. The solution is homogeneous and does not settle out. A solution
cannot be filtered but can be separated using the process of distillation.

1. Sugar water- Homo mixture
2. Soil- Hetero mixture
3. H2O- Pure substance
4. Marble- Hetero mixture
5. NaCL (table salt)- Pure Substance
6. Lava Lamp- Hetero mixture
7. Iron Rod- Pure Substance
8. Kool Aid- Homo mixture
9. Diamonds- Pure substance (Made of Carbon)
10. Tea- Homo mixture

A suspension is cloudy and heterogeneous. The particles are larger than 10,000 Angstroms
which allows them to be filtered. If a suspension is allowed to stand the particles will separate
out.

# data[].attributes.body
is intermediate between a solution and a suspension. While a suspension will
separate out a colloid will not. Colloids can be distinguished from solutions using the Tyndall
effect. Light passing through a colloidal dispersion, such as smoky or foggy air, will be
reflected by the larger particles and the light beam will be visible. A hydrocolloid can simply be
defined as a substance that forms a gel when it comes in contact with water. Such substances
include both polysaccharides and proteins

Characteristics and Properties of Matter 

# data[].attributes.body
You can describe matter according to its physical and chemical properties
1. Physical Properties- Can be observed or measured without chemically changing the composition of matter.
2. Chemical Properties- Describe how a substance interacts with other substances
Physical Properties Examples-
1. Color
2. Texture
Chemical Properties Examples:
1. Rust (ability to rust)
2. Acidity

Properties of Matter: Extensive and Intensive

# data[].attributes.subject
Properties of Matter: Extensive and Intensive

# data[].attributes.body
Extensive- Any characteristic of matter that depends on the amount of matter being measured.
Examples:
1. Mass
2. Volume
Intensive- Any characteristic of matter that does not depend on the amount of the substance measured.
Examples:
1. Density (M/V mass over volume equals density)
2.Color

# data[].attributes.body
Solids-  Have definite shape and definite volume. Particles are packed together
Liquids- Have an indefinite shape but definite volume. Particles have room to move.
Gases- Have indefinite shape and indefinite volume. Particles are far apart.

Physical Change- There is no change in the identity of a substance
Chemical Change- One or more new substances produced.
Physical Change Examples:
1. Tearing
2. Crushing
3. Sublimation
Chemical Changes Examples:
1. Combustion
2. Acid rain

# data[].attributes.body
Phase changes are Physical Changes:
Freezing point- Liquid to solid
Melting Point- Solid to Liquid
Freezing point equals melting point
Boiling Point- Liquid to Gas
Condensation Point- Gas to Liquid
Sublimation Point- Solid to Gas
