A substance made by combining different materials without a chemical reaction.

A type of mixture in which the substance is so evenly distributed that it is difficult to distinguish one substance in the mixture from another.

A type of mixture in which the parts of the mixture are noticeably different from one another.

Matter that always has exactly the same composition. An element or compound.

A substance that is made from 2 or more elements joined together. It can be broken by extraordinary means.

A substance that cannot ever be broken down into simpler substances.

A characteristic of a material that can be observed or measured without changing the composition of the substances in the material.

The ability of a solid to be hammered without shattering.

A material's ability to allow heat (or electricity) flow.

The temperature at which a substance melts/boils.

A resistance to flow.

measure of the strength of a material

any ability to produce a change in the composition of matter.

A materials ability to burn in the presence of oxygen.

how easily a substance combines chemically with other substances.

some of the properties of the material change but the substances in the material remain the same.

substances react to form one or more new substances.

The state of matter in which materials have a DEFINITE SHAPE and a DEFINITE VOLUME.

The state of matter in which a material has a DEFINITE VOLUME but NOT a DEFINITE SHAPE.

The state of matter in which a material has neither a definite shape nor a definite volume.

Total number of valence electrons and atom wants in its outer shell.

Atoms that lose/give an electron are called cations and they have a positive charge.

Atoms that gain/take an electron are called anions and they have a negative charge.

A bond formed when electrons are transferred from one atom to another

electrons are shared between two atoms to form a bond.

change in which a substance or substances is changed into one or more new substances.

undergo change and are found on the left of the equation

form in a chemical reaction and are found on the right of the equation.

substance that affects the reaction rate without being used up in the reaction.

Two or more substances react to form one new substance.

One compound breaks down into two or more new simpler substances

A reaction where one element (alone) takes the place of another element (replaces) in a compound.

Two compounds exchange positive ions to form two new compounds

A substance reacts rapidly with oxygen. It makes CO2 and H2O Oxygen must be reactant
