how did oxygen get it's name?
152763
The word oxygen derives from two words in Greek, οξυς (oxys) (acid, sharp) and γεινομαι (geinomai) (engender). The name "oxygen" was chosen because, at the time it was discovered in the late 18th century, it was believed that all acids contained oxygen.

Oxygen Facts\nAtomic Number  8\nSymbol  O\nAtomic Weight  15.9994 \nDiscovery  Joseph Priestley; Scheele 1774. \nElectron Configuration  [He]2s22p4 \nWord Origin  Greek: oxys: sharp or acid and Greek: genes: born, former... 'acid former'. \nIsotopes  Nine isotopes of oxygen are known. Natural oxygen is a mixture of three isotopes. \nProperties  Oxygen gas is colorless, odorless, and tasteless. The liquid and solid forms are a pale blue color and are strongly paramagnetic. Oxygen supports combustion, combines with most elements, and is a component of hundreds of thousands of organic compounds. Ozone (O3), a highly active compound with a name derived from the Greek word for 'I smell', is formed by the action of an electrical discharge or ultraviolet light on oxygen. \nUses  Oxygen was the atomic weight standard of comparison for the other elements until 1961 when the International Union of Pure and Applied Chemistry adopted carbon 12 as the new basis. It is the third most abundant element found in the sun and the earth, and it plays a part in the carbon-nitrogen cycle. Excited oxygen yields the bright red and yellow-green colors of the Aurora. Oxygen enrichment of steel blast furnaces accounts for the greatest use of the gas. Large quantities are used in making synthesis gas for ammonia, methanol, and ethylene oxide. It is also used as a bleach, for oxidizing oils, for oxy-acetylene welding, and for determining carbon content of steel and organic compounds. Plants and animals require oxygen for respiration. Hospitals frequently prescribe oxygen for patients. Approximately two thirds of the human body and nine tenths of the mass of water is oxygen. \n\nOxygen can exist in a number of physical forms. Most commonly it is found as a diatomic O-O gas and is called molecular oxygen (O2) or dioxygen. The gas exists as a triplet state but the singlet oxygen can also be formed and is more reactive. This gas can be liquefied at low temperatures to produce a blue liquid oxygen (LOX) and cooled further produces a blue solid. After electrical discharge or photolysis Oxygen may also form the triatomic ozone (O3) and under very extreme conditions atomic oxygen (O•) is produced.

The total amounts of oxygen atoms equal to six.\n\nHowever, 3 O2 means there are three molecules of diatomic oxygen atoms, and 2 O3 means that there are two molecules of triatomic oxygen atoms.\n\n3 O2 ( "-" shows bonds)\n\nO-O  O-O  O-O = 6 total\n\nO-O-O  O-O-O = 6 total

How did the world get its name? It just happens.

Their is more Nitrogen in the air than oxygen, because it is a very stable molecule (N2), it takes a lot of energy to react nitrogen gas with respect to Oxygen, oxygen is very reactive, (it is an oxidizer) so  a lot of reactions can happen  (ie. rust forming or combustion reactions) it is also good to note that because of this, that oxygen is the 2nd most abundant element in the earth's crust primarily found in mineral form (i.e. silicon dioxide = sand)

OH LET ME THINK.....WHAT IS THE GAS THAT HELP US HUMAN BEINGS TO LIVE...HMM.....WHAT IS IT CALLED?....OXYGEN? WELL, SERIOUSLY, ITS MIXED WITH OTHER NATURAL GASES.

Actually its MgO. Magnesium is a bivalent metal Mg(2+) and Oxygen has a charge of O(2-) so they form a very strong 1:1 bond.

There's no separation of molecular oxygen to atomic oxygen as previously written:\nsimply \nOx: Sr -> Sr2+ + 2e \nRed: O2 + 4e -> 2 O2-

When oxygen combines with combustible material, such as carbon, a great deal of energy is released.  You and I get our energy from these reactions (and life depends on energy).  However, not all life on earth uses oxygen for energy.  Anaerobic bacteria, for instance; the name means "no air", and oxygen kills them.\n\nAlmost all the oxygen in our atmosphere was originally released by living things, and it was poisonous to the first life!  One of the most remarkable things about using oxygen is that Life adapted to what was originally a deadly poison, until it became a necessity.

1. Because it was called water beofore anyone knew it's composition\n2. Because there are common names for a lot of common chemical compounds\n3. It is easier to use a common name for something as common as water.\nI am going to have some calcium carbonate(I think that's the one) on my chips and a glass of dihydroxide. That sounds silly, doesn't it?

haha the answer above me is funny...what what exactly do you want to know about it? theres a lot to do with respiration...theres inspiration where the air is taken in..this is caused by a contraction of the diaphragm..thens there structures like the epiglotis, trachea, pharynx...then the oxygen goes to your lungs..where gas exchange occurs in the alveoli's...this is done by some complicated process that i dont understand really..i didnt really pay attention during this part of physiology/biology class. haha. anyway, the oxygen is picked up by the pulmonary artery and goes to the rest of the body through the aorta...uhh, i can think of anything else..hope this helps!

Oxygen (as O2) enters the lungs and diffuses through the thin layer of epithelial cells into the blood stream, where it binds one of four sites on hemoglobin.  The hemoglobin carries the oxygen to the heart, where it is then pumped out to the tissues of the body.  Tissues uptake oxgen as needed, and give CO2 in return to the blood stream.  The CO2 is then carried back to the lungs, where more oxygen is taken up.\n\nOxygen serves as an oxidizer, while fuels (such as sugar and fats) serve as reducers.  The oxygen acts in what are called "Oxidation/reduction" reactions (aka Redox--defined by a transfer of electrons) which release an excess of energy.  That energy is used to make ATP (adenosine triphosphate), which acts as the energy carrying molecule of choice by the body.  The systems used to make ATP are primarily glycolysis and the electron transport chain.

Typical Oxygen is O2 and it shares 2 electrons with each other. If you need the charge it is -2 meaning it is looking to gain 2 electrons to be neutral.

You name chemical compounds by the elements that it is made of and the way atoms are organized. For example, CO's chemical name is carbon monoxide because it is made of one Carbon and one Oxygen. Oxygen changes its name to oxide everytime you name chemically. We add mo- to oxide because mo- means one. So monoxide means one oxygen. Carbon stays the same. You don't have to add any prefix or suffix to the word.\n\nIf you need any further explaination, e-mail me at nico_guerrero1991@yahoo.com

Water. Water contains two hydrogens and one oxygen. It's technical name should be dihydrogen monoxide, but we knew about water before chemistry was officially developed.

I believe the name "Earth" is derived from Latin. The ancient Greeks however considered earth a goddess naming her Ge or Gaeia in English translation. They still use the name today for earth in their language.
