Historical Information
http://scienceforkids.kidipede.com/chemistry/atoms/pictures/oxygen.jpg
Element Name : Oxygen
Element Symbol:O
Atomic Number:8
Atomic Mass:15.999
State Of Matter :Gas/Liquid
Color: Gas-colorless/ Liquid-pale blue
Element Group Name : Nonmetallic
Was first discovered by Joseph Priestley and Carl Scheele in 1774 England, Sweden. The word oxygen came from the greek word "oxy genes" meaning acid(sharp) and forming (acid former).Leonardo da Vinci suggested there must be 2 more different gasses in air. Before that they considered air as 1 element. Before 1772 there was a bunch of workers studing air and oxygen was in there but they did not reconize oxygen as an element. Joseph Priestley was credied for finding oxygen but Carl Scheele did an report alone. Joseph Priestley found oxygen by heating lead.

In this picture there is a girl who is breathing in oxygen. Many people/things depends deeply apond oxygen. The most important use of oxygen is life. All living things, with the exception of a few types of bacteria, need oxygen. The only reason that Earth contains free oxygen now is because of the photosynthesis process of green.Carbon Dioxide is often mixed with the oxygenplants
