Compounds

Pure substance composed of two or more different elements

joined by chemical bonds.

Made of elements in a specific ratio

that is always the same

Has a chemical formula

Can only be separated by

chemical means, not physically

Pure Substances

A sample of matter that has definite chemical and physical

properties.

Can you identify the following?

You will be shown a series of photos. Tell if each photo

represents an item composed of an element, compound, or

mixture.

Review:

An element contains just one type of atom.

A compound contains two or more different atoms joined

together.

A mixture contains two or more different substances that

are only physically joined together, not chemically.

A mixture can contain both elements and compounds.
