Classification of Matter

The material is anything that has mass and occupies space.
The Material of pure substance and mixture
1. Pure substance : element and compound
    Element is a pure substance that can not be described again into other substances by ordinary
    chemical reaction.
    In nature there are 92 kinds of natural elements and the remaining elements of the artificial. The
    total number in the wild there are approximately 106 elements.
    Elements are grouped into 3 parts:
    a. Metal element

                                                           ex: copper 
    b. Non-metal elements

                                              ex : Hydrogen and Oxigen 
    c. Semi Metal elements

                                                                   ex: silicon
   Compound : is a pure chemical substance consisting of two or more elements. That can be separated into Simpler substances by chemical reactions. [4] which can be broken down again into its constituent elements by chemical reaction them. For example, dihydrogen monoxide (water, H2O) is a compound consisting of two hydrogen atoms for every oxygen atom.
 
2. Mixture : solutions, colloids and suspentions
   Solutions : salt solution, sugar solution.
   Colloids : milk, ice cream, jely
   Suspentions : sand +water, coffe+water, river
