In research, argon gas is either directly applied to cells in a culture dish that are under stress, such as an oxygen- and glucose-deprived environment, or given mixed with oxygen in a facemask for animal studies. But in space, argon is made in stars, when a two hydrogen nuclei, or alpha-particles, fuse with silicon-32.

As you can see in the image above, argon gas produces a lovely bluish-purple colour when excited with electricity. And thus compounds of argon of any description would be vanishingly few. Argon is unreactive because it has the maximum number of electrons in its outer shell. (Although, the noble gases are much prettier than most video gamers when stimulated with electricity.). When I was a kid, I was first introduced to chemistry. Live Science is part of Future US Inc, an international media group and leading digital publisher. No one yet understands why argon has this effect.

Relying on their knowledge of how these elements come about, they can make inferences and draw conclusions about the history and compositions of these planets.

Argon is element 18 on the periodic table, which means that it has 18 protons in its nucleus.

Unlike other resources, Argon Crystals decay after a period of time.

So much so, that it forms compounds with virtually no other elements. Argon is also a good insulator, so it's often pumped into deep-sea diving dry suits to keep the diver warm.

For example, the Martian atmosphere contains 1.6 percent argon-40 and 5 ppm of argon-36, Mercury's thin atmosphere is comprised of 70 percent argon (the relative abundances and identities of the isotopes is not clear), and Titan, the largest and most fascinating of Saturn's many moons, has argon-40 in its atmosphere. There may be one or two fluorides or oxides of argon known; these are exceptional, and their chemistry belongs to a few specialists.

Just like neon (Ne) and helium (He), argon (Ar) usually floats around all by itself. How can the periodic table be used to predict the properties of the elements? The gas is pumped around important documents such as a map of the world dating back to 1507 in the Library of Congress, and a copy of the Magna Carta held by the U.S. National Archives. All rights reserved. 716 views By no means is argon reactive. Argon is the third noble gas, in period 8, and it makes up about 1% of the Earth's atmosphere. Argon's chemical inactivity results from having an outermost shell of electrons that is completely filled, so it isn't attracted to any other atoms (which is how chemical bonds are formed). Will our solar system survive the death of our sun?

According to the octet rule, most elements need to have 8... Our experts can answer your tough homework and study questions.

Xenon, however, is expensive, leading researchers to turn to its noble gas cousin, argon, as a potential alternative. According to the octet rule, most elements need to have 8...

Argon is a Noble Gas, and on account of its closed shell electronic structure, it is (i) difficult to oxidize, and (ii) difficult to reduce. Argon is unreactive because it has the maximum number of electrons in its outer shell. According to the Jefferson National Linear Accelerator Laboratory, the properties of argon are: The first hint of argon's existence came in 1785, when British scientist Henry Cavendish reported a seemingly inert portion of air, according to the RSC. Cavendish wasn't able to figure out what this mysterious 1 percent was; the discovery would come more than a century later, in 1894. Based on these data, what conclusions can you make about the likely source for these argon isotopes, and what inferences can you make about these planetary bodies? By no means is argon reactive . While investigating the element, he also discovered helium, according to the Nobel Prize organization. Argon is an inert, colorless and odorless element — one of the Noble gases. Argon is a chemical element with atomic number 18 and symbol Ar. But besides that, what use does argon have? It has a filled electron shell so under normal conditions it will not form compounds.
