Multiple Choice

The basic building blocks of most of the matter around you.

• elements

• protons

• atoms

• electrons

Multiple Choice

Because an element can not be broken down into a simpler substance, it is considered to be

• a chemical substance

• a pure substance

• unbreakable

Pure Substances

Pure substances cannot be broken apart by physical means. There are two types.

Elements, which cannot be broken down any further and Compounds, which can only be separated into elements by breaking chemical bonds (not easy to do).

Mixtures

Mixtures are any substances that can be split apart physically. There are two types of mixtures.

Heterogeneous mixtures are ones that you can see the different parts clearly.

Homogeneous mixtures are ones you cannot see the individual pieces within.
