The Classification of Matter

The Classification of Matter

Learning Intentions

• I can classify matter (element, compound, heterogeneous mixture, and homogeneous mixture) and justify my answer with an explanation using scientific language

Matter

• Matter is anything that has a mass and takes up space

• Mass is the amount of matter that an object has

• Volume is the amount of space that an object fills.  

Matter

• All matter can be classified as either a pure substance or a mixture

Pure Substance

• A pure substance is matter that contains only one type of particle

• Example: copper wire is made from only copper particles. 

Pure Substance

Pure substance can be further classified as elements or compounds

Element

• An element is a pure substance that can’t be changed into anything simpler

• Today we know there are at least 116 elements.  

• Examples: copper & gold.

Compound

• A compound is a pure substance that consists of two or more elements

• Compounds have only one kind of particle, but each particle consists of two or more elements. 

• Example: water

Mixture

• A mixture contains two or more pure substances.

• Example: table salt dissolved in water or iron mixed with sulfur.

Mixture

• A mixture is formed when two or more pure substance are put together

• Example: Fertilizer

Heterogeneuos Mixture

• A heterogeneous mixture is not uniform in its composition

• The particles can be visibly distinguished in large visible clumps

• Example: oil and water, cement 

Homogeneous Mixture

• A homogeneous mixture is made of substances that are evenly and microscopically mixed together

• Example: soda pop, the air we breathe, alloys
