Atoms

100

This type of matter consists of 2 or more substances NOT

chemically combined.

Mixture.

100

This part of the atom has a positive charge.

Proton

100

The modern Periodic Table shows these, arranged in

increasing atomic number.

Elements

100

This is the study of the properties of matter and

how matter changes.

Chemistry

100

These would have a pH value of 0-7.

Acids

100

The combination of 2 or more atoms.

Molecules

200

Burning wood is an example of this kind of change.

Chemical

200

This type of mixture can be separated by gravity.

200

Soap and detergents are examples of these.

Bases

200

2 or more elements chemically combined in a

specific ratio.

Compound
