A mixture contains two or more different types of matter.
Heterogeneous mixture is made up of different parts that you can detect quite easily.
Homogeneous means that every part of the material is the same as every other part. Must be a solution (if a mixture) or a pure substance.
Pure substances are the same throughout (homogeneous).
Mixtures that are clearly heterogeneous are mechanical mixtures.
A heterogeneous mixture in which the partical settle slowly after mixing is called suspension.
A suspension that has been treated with an emulsifying agent is called an emulsion.
Homogeneous mixtures are called solutions.
The solute is the substance that dissolves.
The solvent is the substance in which the solute dissolves.
An element is a pure substance that cannot be broken down or seperated into other pure substances.
A compound is a substance that is made from two or more elements that have combined in a chemical change. Water (H20), Salt (NaCl), and Sugar (C6H12O6) are examples of compounds.
There are 92 elements that exist naturally and 24 elements that can be made in a labratory. Scientists have listed these elements in a table called the periodic table.
All matter is made up of small particals called atoms. Atoms are the smallest building blocks of matter.
When two or more atoms link together, a molecule is formed
