Atoms Elements Molecules Compounds Pure Substance Mixture Solution

Atoms Are the smallest particle of an element that still retain the properties of that element

Elements are made of only one type of atom (element). Aluminum Copper Hydrogen Fluorine

Compounds are made of two or more types of elements. Water Carbon Dioxide Salt Sugar

Molecules two or more atoms joined together in a chemical bond. This is a water molecule, H 2 0…

Pure Substance a pure substance has only one type of element or compound.

A mixture has two or more elements or compounds mixed together but not chemically combined.

A solution is a very well mixed mixture, like salt water. You cannot see the salt, but it is there.
