Pure Substances● A sample of matter that has definite chemical and

physical properties.

Page 3: Classifying Matter: Elements, Compounds, and Mixtures · Classifying Matter: Elements, Compounds, and Mixtures. Pure Substances A sample of matter that has definite chemical and physical

Elements● pure substance that cannot be separated into simpler

substance by physical or chemical means.

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

Mixtures!

● A combination of two or more pure substances that are not chemically combined.

● substances held together by physical forces, not chemical ● No chemical change takes place ● Each item retains its properties in the mixture ● They can be separated physically

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.
