Carl Wilhelm Scheele & Joseph Priestly

Two people actually discovered oxygen. The first man to discover it was a Swedish Chemist, Carl Wilhelm Scheele. The second man was a man by the name of Joseph Priestly, an English chemist. The first discovered oxygen in 1772 and the next in 1774.

Picture of the element-



liquid oxygen oxygen in tank

You cannot see oxygen. But you can see liquid oxygen,this is what liquid oxygen looks like. In the picture you can barely see the pale color. oxygen can not be seen so it is placed in a container that can hold it in, people can use it for various needs.

B-Physical properties- Oxygen is a colorless odorless gas. You can not feel it and you cannot taste it or see it. Yet oxygen can be seen if in a Liquid or a solid form. When in this form it is a pale blue color.



1. Oxygen can be turned into a solid; it’s not only something we breathe! And when it’s a solid or liquid form, it is a pale blue color. Both liquid and solid oxygen were first made in laboratory's, neither are found in nature. 2. About 2/3 of your body’s mass is made up of oxygen, cause your oxygenated blood platelets carry it to diferent parts of your body. 3. Almost each person has an average of 60%-70% of oxygen in their blood cells. But it is a proven fact that sometimes when our oxygen level in our blood stream is way too low we develop harmful diseases, like cancer, or leukemia! 4. We use oxygen in about everything we do. We have it in water, we need it to breath, and we get it from some plants like trees and flowers.Everywhere we go we use oxygen!

1. Does your mom make you take vitamins? Well it turns out that there’s liquid oxygen in your Vitamins! 2. The liquid oxygen is used in rockets as a reserve for use as a fuel engine. Another words, this means that the liquid oxygen is used to force the fuel into accelerating the ships upward. This is not only in rocket shipsbut also in race cars and other machines. 3. Oxygen is also used for many medical problems; it is used for respiratory problems, oxygen therapy, life support, even in nutritional bars. 4. Some welding torches require not only fuel, but liquid oxygen to cut pieces of metal. This type of welding is called oxy-fuel welding it was discovered in the 1900's, it's been used for many years.
