Types of Matter

Solution

• A mixture of two or more substances that are not evenly distributed.

• A chemical reaction that produces a new substance.

• A physical change that alters the state of matter.

Chemical Bond

• The sharing or transferring of electrons to connect atoms together.

• A type of physical change in matter.

• A process of breaking down molecules into simpler substances.

• A method of measuring atomic mass.

Molecule
