__**//Oxygen Can Be Yours Today!!!//**__ Oxygen is the essential element to meet your respiratory needs! If you don’t purchase oxygen atoms for daily use, then your inward breaths will consist only of nitrogen, as well as a little carbon dioxide and argon. Uh-oh. Don’t settle for second best! Your brain needs __oxygen__ to function, not those other guys. Carbon Dioxide is not close enough. Oxygen is the only element that allows the body's cells to release energy, so that you can move at all. So shoose oxygen, “We promise a working brain and a living body.”

//**__The Properties of Oxygen!__**//

Physical properties of oxygen include its cubic crystal structure, boiling point of -183 degrees C,melting point of -218.4 degrees C and it’s colorless, tasteless and odorless presence.

The chemical properties of oxygen are that it’s the essential element in the respiratory processes of most of the living cells and in combustion processes. Oxygen supports combustion, combines with most elements, and is a component of hundreds of thousands of organic compounds.Oxygen can be separated from air by fractionated liquefaction and distillation. It is a very reactive oxidising agent. Oxygen’s paramagnetism is strong, liquid oxygen is also slightly paramagnetic. Every element, except fluorine and the noble gases, combine spontaneously with oxygen at galactic standard temperature and pressure. The singlet form of oxygen reacts with almost all compounds. Molecular oxygen is a stable diradical. It has two electrons in an unpaired triplet state; oxygen is the only naturally occurring chemical with this property. Oxygen’s electronegativity is 3.4, heat of vaporization: 3.4099 kj/mol, heat of fusion: 0.22259 kj/mol, and its first ionization energy: 1314 kJ/mol. The electron configuration of oxygen is 1s2 2s2 2p4.

**__//Why Choose Oxygen???//__** Oxygen is certainly the most useful of all the elements.It is essential to human respiration. If you or someone you love has breathing problems, then large quantities of oxygen need to be utilized to operate breathing machines. Space suits need a storage of oxygen so that astronauts can breathe. Don't be fooled though, oxygen has other uses besides breathing.This element is used to produce extremely high temperatures to melt metals,so that they can be molded and cut into every day materials. Oxygen is used to make different substances react faster and to ensure the greatest oxidation of undesired compounds.

Oxygen when compared to elements with similar properties such as sulfur, selenium, tellurium, polonium, and ununhexium is comparably more useful. Oxygen is the most abundant of all of these elements, which means that it’s much easier to obtain and a lot less expensive. It’s also the most useful of all the elements because it is present in many compounds. Two of these compounds are water and carbon dioxide. Ununhexium is not very useful and can only be used in scientific experiments! Oxygen is regularly available and therefore much easier to access for daily use, the most recommended dosage.

<span style="font-family: 'Trebuchet MS',Helvetica,sans-serif;">Due to oxygen’s abundance it is not typically highly priced in the form of air. Oxygen in air form is practically free! (Give or take a few precautions i.e. pollution.) Oxygen is available in many compounds though such as water. Oxygen as a part of water is a little more expensive. On average Americans spend $15 billion a year on bottled water. So depending on what you’re looking for oxygen can be fairly priced!

It is output into the atmosphere by plants. <span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 110%;">- Blood is red as a result of the bonding between oxygen and haemoglobin. <span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 110%;">- Discovery of oxygen is accredited to Carl Scheele, and Joseph Priestly, who were the first able to credit its significance in causing materials to burn. Their recognition, however, is shared with Joseph Priestly, who named the element and was able to grasp its full significance. H proved that oxygen is the reactive component of air (Lane).
