During this project we were assigned to research Oxygen. The elements in group 16 of the Periodic Table of Elements are Sulfur, Oxygen, Selenium, and Tellurium. The symbols for these elements are O for Oxygen, S for Sulfur, Se for Selenium, and Te for Tellurium. They are all located in the row, or group 16 on the Periodic Table of Elements. The period for the element Oxygen is 2, Sulfur is 3, Selenium is 4, and Tellurium is 5. The elements in the oxygen group exsit in all three forms. The liquids and the solids are in forms of a pale blue color. Something interesting about this is that oxygen is the third most plentiful element found in the sun. Also Oxygen is responsible for the bright green and yellow colors in the aurora.===== The Oxygen groups atomic number is 8. Also it's mass number is 15.9994. Something else that is interesting about this group is that it's electron configuration is 1s22s22p4. It's atomic Radius is 74 pm. Lastly it's Ionic radius is 140 (O2-).

**__Elements:__**
1. Sulfur 2. Oxygen 3. Selenium 4. Tellurium

**__Physical Properties:__**
1. Oxygen has a crystal structure. 2. Oxygen is colorless, odorless, and has no taste. 3. Oxygen's boiling point is 183 degrees Celsius and it's melting point is 218 degrees Celsius

**__Chemical Properties:__**
1. The Oxygen Group helps other things burn. 2. The Oxygen Group and many compounds react with each other. For example, Decay. 3. Also, room temperature oxygen combine with other elements. For example, Rust.

**__Interesting Facts:__**
1. Oxygen is needed for all animal life on earth. 2. Scientists usually don't make it labs because it is already in the air from the plants, and it would come into the room somehow. 3. Oxygen is the most important element. With out there would be no life on earth.

A common use is that Oxygen is what we breathe in. Trees and plants inhale Carbon dioxide and exhale oxygen for us to breathe. Another common use is that doctors use oxygen in Medicines.
