Material

A type of solid matter used to make things

Property

A particular characteristic and/or trait. (Physical and Chemical)

Physical property

A property that can be identified, or measured, and does not rely on testing if the material reacts with another substance, like color.

Mass

A measurement of the amount of matter in an object or system.

Volume

The amount of space that an object or substance occupies.

Density

The relationship between the mass and volume of a substance. The mass per unit volume, specifically grams per cubic centimeter, or grams per milliliter.

Calculating density

Mass divided by Volume (m/v)

Solubility

The ability of a substance to dissolve in another substance.

Malleability

The flexibility of a material.

Chemical property

A specific result of a test with a chemical reagent. Include pH, the production of a salt when an acid reacts with a metal, or a unique color change in a chemical reaction.

Atom

The building block of matter

Element

A substance that cannot be broken down into simpler substances by chemical or physical means.

Compound

A pure substance composed of two or more essentially different elements that are chemically combined and that are thus present in definite proportions.

Molecule

Two or more atoms held together by chemical bonds. The smallest particle of an element or compound that displays the properties of the substance in quantity.

Chemical bond

The electrical attraction between two different atoms that forms a molecule.

Life cycle

The progression through a number of steps or different stages in the manufacture, use, and disposal of a product.

Life-cycle diagram

A diagram that illustrates the stages in the manufacture, use, and disposal of a product.

Matter

The stuff that makes up all living and nonliving objects.

Extended Structure

A varied number of one or more kinds of atom bonded together to form a large network.

Coefficient

A number in front of a chemical formula in an equation that indicates how many molecules or atoms.

subscript

A number in a chemical formula written behind and below the atom that tells the number of atoms in a molecule.
