Radioactive potassium-40 becomes into as it is decayed. 33. Argon is the third-most abundant gas in the Earth's atmosphere, at 0.934% (9340 ppmv). Medical use: Liquid Argon is used to damage tissues such as cancer cells. To ensure that all traces of Oxygen are removed from the apparatus, he further made use of Potassium Polysulfides. The list of Argon facts in this article will take you through the history (and discovery) of the element. Argon is extensively used as a preservative. It was the first noble gas to be discovered. It is a known fact that Nitrogen oxides are all acidic by nature. Inhalation of this gas also causes dizziness, dullness, headache, nausea, vomiting and even death if inhaled in large proportion. terms and conditions. Liquid Oxygen boils at 90.2 K. 83. 49. William Ramsay was the person who was responsible for either discovering or co-discovering most of the noble gases that we know today. Some of the argon-36 adds an alpha particle to become calcium-40. However, if you see a Neon light with a blue glow, you should immediately know that Argon is present in the light. Because Carbon dating is often inaccurate, scientists often go for Potassium-Argon dating or Argon-Argon dating.
Despite Cavendish’s failure (or success – whatever you call it), he was way ahead of his time. It is produced in Industry by air fractionation of liquid air. In the year 1892 came famous scientist – Lord Rayleigh.

In particular, Cavendish was very dissatisfied with the lack of information about that part of the air that was not Oxygen. Rayleigh and Ramsay removed the nitrogen, oxygen, water, and carbon dioxide and examined the remaining gas. 46. Argon is a group 18 chemical element, which is the noble gases group. 36. Argon is used to cool the heads of heat-seeking missiles.
9. In Earth's atmosphere, almost all of the argon is radiogenic-argon-40, which is derived from the potassium-40 decay in the Earth's crust and in the universe; argon-36 is the common argon isotope. Potassium-40 (which is radioactive) is known for decaying into Argon-40 (stable isotope), and Calcium-40 (stable isotope). Their experiment was to remove all of the nitrogen, oxygen, carbon dioxide, and hydrogen dioxide from pure air, and isolate the remaining gas. 45. The element was isolated and officially discovered in air by Lord Rayleigh and William Ramsay in 1894. It acts as a barrier to Oxygen. How much of Argon is present in the atmosphere of our Earth? He made Nitrogen and Oxygen in the air to react by passing an electric spark. Of course, the two scientists stayed in close contact to ensure that they are aware of each other’s progress. Liquid argon is used in cryosurgery, to destroy cancerous tissue. Another element called Mendelevium received a new symbol that same year. 14. The new symbol that came into existence for the gas was ‘Ar.’, 44. 72. Rayleigh was not wrong during his Nobel Prize speech! No stable compounds are known at room temperature and pressure. Once the problem was posted, it became an opportunity for any scientist to discover a completely new element. 25. It is used to produce scintillation light.

27. It's used as a protective gas for welding, storing sensitive chemicals, and protecting materials. This observation led Cavendish to conclude that at least 99.3% of the air was made up of Nitrogen, Carbon Dioxide, and Oxygen. It is widely used in lighting.

Trivial name of Argon is noble gases*, aerogens. Worldwide over 771 million tons of argon gas are produced annually.

The two then started experimenting together (albeit in their own countries). Scientists make use of Argon-Argon technique for more precision dating. For instance, in scientific research, Argon gas is directly used for searching dark matter! Do you know what Carbon dating is? Hartley in 1882 revealed a spectral line that could not be assigned to any known element. Once our new domain is ready and the articles are published, we will formally launch the new site. In their combined paper, Ramsay and Rayleigh stated that the newly discovered element did not react with any known thing. 61. Argon constitutes 1.288 percent of the atmosphere by weight and 0.934 percent by volume and is found occluded in rocks. 8. 39. He took air and removed Nitrogen, Carbon Dioxide, and Oxygen from it. Argon is a period 3 chemical element, which is the third row on the periodic table. 51. Most of the argon on Earth comes from the radioactive decay of potassium-40 into argon-40. The element name "argon" comes from the Greek word. This amazing find managed to upset many archeologists because it simply went against the existing notion, discarding hundreds of literary work done previously. 60.

Interesting Facts about Argon. Compared to that, Earth’s atmosphere is made of 0.94% Argon. Argon emits a blue-violet glow when it is excited. In Earth's crust, Argon is the most plentiful noble gas, comprising of 0.00015% of the Earth’s crust. 7 few quick facts about Argon Gas Argon is the 3rd noble gas, in period 8(p-block) of the Periodic table, it makes up about 1 percent of the Earth's atmosphere. It was the first noble gas to be discovered. But in 1894, Argon was first isolated from the air at London University College, by William Ramsay and Rayleigh by detaching carbon dioxide, oxygen water, and nitrogen from a sample of air. Copyright © 2020 Facts Just for Kids. Did you know Argon is also present on Titan (satellite of Saturn) and in the atmosphere of Mercury? Argon Facts: 51-55 | Fun Facts about Argon You Cannot Miss. Argon is a noble gas element. Ar-39 in earth’s atmosphere is made using cosmic-ray activity. Argon has replaced helium for that purpose, as it does not leak as quickly.

Argon may be used to make a breathing mix called Argox to help remove dissolved nitrogen from the blood during decompression, as from deep-sea diving. 79. Divide that volume of Argon in the atmosphere, and we get 9+ metric tons of Argon for every single person on the planet. In Earth’s atmosphere, Argon is the 3rd most abundant gas. 10 Argon Facts Argon is a colorless, flavorless, odorless noble gas. Argon is a colorless, odorless, and tasteless gas. This gas in the environment occurs naturally and it also doesn’t constitute any chemicals which can result in ozone depletion. The ‘something else’ that Cavendish found was unreactive – very unreactive. By far the majority (over 99%) of argon found naturally on Earth is argon-40. 35. Ramsay immediately knew that he discovered a completely new element. 62. 41. The standard atomic weight of argon is 39.948 u. Argon is in the noble gas element category on the periodic table. Do you wish to be a superstar in your class? 99% of the Argon we find on Earth is Argon-40 produced from Potassium-40. NASA probes found this? Previously Mendelevium was denoted as ‘Mv.’ The new symbol that IUPAC selected was ‘Md.’. He used Magnesium to react Nitrogen with it.
