How Oxygen is Extracted


Q: Anyone know any jokes about sodium? 
A: Na


Hey like you probably already know my names Oxygen but you can call me Oxy.


So people often ask me what it would take for me to leave my awesome group air. I mean we are already incredibly successful and most people would die if we spilt up. However some people want to see me debut as a soloist for some reason so I've decided to put out my standards of what it would take to separate me from air. My first requirement would be to put me, nitrogen and everyone else that makes up air in an industrial air separation plant and have us decompressed and compressed until our temperature cools down enough for us to become a liquid. Then 75% of the liquid would be nitrogen and the other 25% would become me. From there since nitrogen and I reach boiling points at different temperatures we can be separated easily.

Where is Oxygen Found in Nature


Q: What is "HIJKLMNO"?
A: H2O


Hey I'm oxygen, but you probably don't need this intro anymore. Here are some things you need to know, or maybe you just forgot.


I make up 21% of the earths atmosphere which is about  1.189 quadrillion metric tons. I'm nine tenths of water, and I'm two thirds of the human body, (which is 66% in case you were wondering). I'm 47% dry soil. I'm 85% of sea water, 42% of all vegetation, and 50% of the crust of the Earth by weight.


Again I'm part of hundreds of thousands of organic compounds. And without me, life wouldn't be possible. Even though 15 isotopes of oxygen exist, natural oxygen is a mix of 3 isotopes. Most living cells need me, and it's no problem because I'm the 3rd most abundant resource in the universe..

When was Oxygen Discovered and by Whom

Q: If H2O is water, what is H2O4?
A: Drinking, bathing, washing, swimming, etc...


Hey I'm oxygen, but you probably don't need me to tell you that.


In 1772, Carl Wilhelm Scheele discovered oxygen for the first time. But before Carl Wilhelm Scheele could publish his findings, Joseph Priestly, an English chemist, beat him too it in 1774, 3 years before Scheele even got the chance to. And a french chemist, Antoine Eavoisier, discovered oxygen as an element is 1775.


Carl Welhelm Scheele
There was a huge dispute about who discovered me first. But I'll just stick to Scheele being my real founder.

Pros and Cons of Oxygen

A neutron walks into a bar. He asks the bartender, "How much for a beer?" The bartender offers him a warm smile and say, "For you, no charge."


Hey I'm oxygen, but you probably already knew that by now. You might not see me around, but I'm used for more than what you think I am. Here are things you need to know, or maybe you just forgot.


For conditions like emphysema and pneumonia, oxygen therapy is used. Oxygen gas is poisonous to bacteria that causes gangrene. So I'm used to kill it. Carbon monoxide poisoning is treated using oxygen gas. Near pure oxygen is used in space suits and scuba tanks, (but for the scuba tanks I'm normally mixed with regular air). Oxygen tanks are also found in submarines and airplanes, (but they're only used for emergencies). Rockets use liquid oxygen to burn fuel and generate lift. Commercially produced oxygen converts iron ore into steele. Scientists use the ratio of 2 isotopes of oxygen (18 and 16) in skeletons to find what the climate was like thousands of years ago. Pure oxygen is used to ensure the complete combustion of different chemicals. Oxygen is used to treat water and cut and weld metals.




Oxygen Therapy




That's mostly what our modern society uses me for. Most living cells use oxygen too, but that's obvious. This is pretty much the end of the list. However aside from being all good, I can also cause harm. I have the power to rust and eventually damage strong metals like iron, increase the chances or rapid spreading of fire and explosions and even damage cells of living beings that rely on me to survive. This is known as oxygen toxicity which is a concern for people breathing in high concentrations of supplemental oxygen regularly which can harm their lungs.


When using me be aware that there are no:



  • Open fires.
  • LPG or other fuel gases (includes gas stoves and gas fires).
  • Oils, including cooking oils and lubricating oils.
  • Petrol, kerosene and paint solvents..

Physical & Chemical Properties of Oxygen

A proton and a neutron are walking down the street. The proton says, "Wait, I dropped an electron help me look for it." The neutron says, "Are you sure?" The proton replies, "I'm positive."


Hey my name is oxygen. I'm an active life sustaining part of the atmosphere. I make up 90% of water and I make up two thirds of you ! Here are things you need to know, or maybe you just forgot.


I am a colourless, odourless and tasteless gas. I boil at 183 degrees Celsius and melt at 218.4 degrees Celsius. I have a density of 0.001429 g/cm3 and I exist in all 3 forms. But my liquid and solid form are a pale blue colour, as well as I have a cubic crystal shape. In my liquid form I'm potentially hazardous about flames and sparks as I will greatly accelerate combustion, but I do not burn myself in the reaction. I'm chemically active meaning I from compounds with practically every element but the inert gases. I'm not a good conductor of heat or electricity, but that's alright. These are only physical things about me. Now what I need you to know are the chemical.


I'm essential in the respiratory process and the combustion process. I combine with most elements, and am a component of hundreds of thousands of organic compounds. I'm a very reactive oxidizing agent. Oxidation means that a molecule, atom or ion has lost electrons in a chemical reaction which makes me an atom that likes to gain electrons. What you also might not know is that the ozone, (O3) is also a powerful reactive agent.


There is also other things to know about me, like how my paramagnetism is strong. But this stuff isn't even that important, and it's going to go way over your heads, so I'll just keep it simple for now.

Hi My Name is Oxygen

Hey my name is oxygen, but my friends call me Oxy. You might not notice me much because I'm a colourless, odourless and tasteless gas. But i make up 21% of the Earth's atmosphere. I'm one of the 5 elements all life is based on, and people call me, "the Breath of Life".


This morning I weighed in at 16 a.m.u's but my weight tends to change a lot. 99.762% of the time I weigh the same as I did this morning but 0.038% of the time I weigh 17 amu and 0.2% of the time I weigh 18 amu. I have a total of 15 different types of weight ranging from 12-28 amu but none of those last very long except for those three I just listed. For instance once I went on this super intense weight loss program because I wanted to become a model (which did not work out, obviously) and I reached my goal of 12 amu which unfortunately only lasted about  580(30)×10−24 seconds.So now I work with my family the chalcogens but if you ever want to talk to just me and not the annoying sulfur or even worse selenium just simply ask for #8 (my atomic number) or just ask for O (my symbol).


Sometimes I don't feel complete. I wish I could be like neon, that element just seems so stable, so noble... But it's alright because I get along with practically every other element. And right now I'm with my buddy, Oxygen. People like to call us O2, we're also known as one of the 7 diatomic molecules. I'll rarely be found on my own, and together, we're pretty stable.


Here's a quick look at what happens when I try to hang out with other people.
