Classifying Matter: Pure Substances and Mixtures Graham

What is Matter? Matter Not Matter

Matter is Anything that has Mass and takes up Space(Volume)

So how do we get all the different types of matter that we see around us. Atoms are the smallest particle of matter. Atoms group together to make up everything around us. They are like bricks in a building.

There are only 118 Different types of atoms. They are called Elements.

All Matter is then separated into 2 Types Pure Substances and Mixtures

Pure Substances sample of matter that has definite chemical and physical properties. H 2 O

periodic table(a list of every known atom) sample of matter that is made up of only the same type of atoms pure substance cannot be separated into simpler substance by physical or chemical means.

Compounds Pure substance composed of two or more different types of atoms and are 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. (no bonding) substances held together by physical forces, not chemical (put together by mechanical means) No chemical change takes place(NO Bonding) Each item retains its properties while in the mixture. They can be separated physically Chem 4 kids. com
