What is oxygen Short answer?
Oxygen is a chemical element. It has the symbol O and atomic number 8. It is the third most common element in the universe, after hydrogen and helium. Oxygen is more than a fifth of the Earth’s atmosphere by volume. In the air, two oxygen atoms usually join to make dioxygen (O.
What is oxygen exactly?
Element No. 8 on the Periodic Table of the Elements is a colorless gas that makes up 21 percent of Earth’s atmosphere. Because it’s all around, oxygen is easy to dismiss as dull and inert; in fact, it’s the most reactive of the non-metallic elements.
What is oxygen made of?
Oxygen is a chemical element – a substance that contains only one type of atom. Its official chemical symbol is O, and its atomic number is 8, which means that an oxygen atom has eight protons in its nucleus. Oxygen is a gas at room temperature and has no colour, smell or taste. Oxygen is found naturally as a molecule.
What is use of oxygen?
Common uses of oxygen include production of steel, plastics and textiles, brazing, welding and cutting of steels and other metals, rocket propellant, oxygen therapy, and life support systems in aircraft, submarines, spaceflight and diving.
Where does oxygen come from?
At least half of Earth’s oxygen comes from the ocean. Scientists estimate that 50-80% of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic plankton — drifting plants, algae, and some bacteria that can photosynthesize.
What is oxygen made of kids?
Under standard conditions oxygen forms a gas that is composed of molecules consisting of two oxygen atoms (O2). This is called a diatomic gas. In this form oxygen is a colorless, odorless, tasteless gas. Oxygen also exists as the allotrope ozone (O3).
Why is it called oxygen?
Where did oxygen get its name? The name oxygen comes from the Greek word “oxygenes” meaning “acid producer”. It was called this because early chemists thought that oxygen was necessary for all acids.
Where is oxygen naturally found?
Occurrence in nature Oxygen occurs mainly as an element in the atmosphere. It makes up 20.948 percent of the atmosphere. It also occurs in oceans, lakes, rivers, and ice caps in the form of water. Nearly 89 percent of the weight of water is oxygen.
Why is oxygen important to life?
Most living things need oxygen to survive. Oxygen helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their nose and mouth into their lungs. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive.
Can we create oxygen?
The most common commercial method for producing oxygen is the separation of air using either a cryogenic distillation process or a vacuum swing adsorption process. Nitrogen and argon are also produced by separating them from air. This method is called electrolysis and produces very pure hydrogen and oxygen.

What are some interesting facts about oxygen?
– Here are 11 interesting facts about oxygen, abundant not only in our planet’s atmosphere, but also one of the most abundant elements in the universe. You can find out much more on our main oxygen page. Dry air is 21 percent oxygen, 78 percent nitrogen and 1 percent other gases. – Oxygen dissolves in cool water easier than in warm water. Without plants, there would be very little oxygen in the air. Water can be converted into hydrogen and oxygen through electrolysis. The oxygen that is found in the air is produced by photosynthesis. – One fifth of the Earth’s atmosphere is made up of oxygen and is the third most abundant element in the universe by mass. Oxygen is the most abundant element by mass in the Earth’s biosphere.
What are 5 uses for oxygen?
Common Uses of Oxygen. This gas is used in various industrial chemical applications. It is used to make acids, sulfuric acid, nitric acid and other compounds. Its most reactive variant is ozone O3. It is applied in assorted chemical reactions. The goal is to boost reaction rate and oxidation of unwanted compounds.
What are three important uses of oxygen?
Oxygen. Common uses of oxygen include production of steel, plastics and textiles, brazing, welding and cutting of steels and other metals, rocket propellant, oxygen therapy, and life support systems in aircraft, submarines, spaceflight and diving .
What are facts about oxygen?
Oxygen Facts. The most abundant chemical element on Earth. Most living organisms, including Animals and Plants require oxygen for respiration. Humans inhale more than 6 billion tones of oxygen each year. Oxygen in gaseous form is colorless, odorless, and tasteless while liquid and solid oxygen are pale Blue in color.
