Because argon is so stable and is a poor heat conductor it is used as a shield gas in arc welding. Argon is used when other non reactive elements become reactive. Argon is the cheapest of all the noble gas. Argon is priced at a measly half a cent per gram.
What is the cheapest noble gas?
Other noble gases would be equally suitable for most of these applications, but argon is by far the cheapest.
Why is argon cheaper?
Argon is inexpensive since it is a byproduct of the production of liquid oxygen and liquid nitrogen , both of which are used on a large industrial scale. The other noble gases (except helium) are produced this way as well, but argon is the most plentiful since it has the highest concentration in the atmosphere.
Why is argon the most abundant noble gas?
This is due to its very stable nucleus and inert properties . It is used to provide inert atmospheres in various reactions which are carried out in laboratories and as well as other uses. Therefore, the most abundant noble gas in the atmosphere is argon.
Why is there no value for argon?
They don’t have values there because they aren’t on the pauling scale of electronegativity, as they don’t form any compounds with other elements. However, argon and neon can technically form compounds with other elements; it is just extremely unlikely.
Why is argon purple?
The argon atom has 18 electrons and 18 protons. Its outer shell is full with eight electrons. Under standard conditions argon is an odorless and colorless gas. ... When argon is excited by a high voltage electric field it glows in a violet color .
What are the 7 noble gases?
Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og) .

Is argon a dry gas?
Argon is the most common gas in the atmosphere besides Nitrogen and Oxygen. Argon is a noble gas (like helium) which means that it is completely inert . Argon will not readily react with any other substance. ... Since it is such a small percentage of the atmosphere Argon is many times more expensive than Nitrogen.
Why is argon called the lazy one?
Argon is an inert, colorless and odorless element — one of the Noble gases. Used in fluorescent lights and in welding, this element gets its name from the Greek word for “lazy, ” an homage to how little it reacts to form compounds.
Does argon have a smell?
Argon is an odorless , tasteless, and colorless gas.
Which gas is most obedient in the atmosphere?
The most abundant gas in the Earth’s atmosphere is nitrogen . The second most abundant gas is oxygen. Both of these gases occur as diatomic molecules. The amount of water vapor is highly variable.
Why do noble gasses not have electronegativity?
Electronegativity is the atom’s ability to attract electrons within a bond. Since noble gases already have a full valence shell of electrons and are stable, they have no need for attracting electrons so no, they do not have electronegativity.
Why argon is a noble gas?
Argon–along with helium, neon, xenon, radon, and krypton–belongs to the so-called “noble” gases. Also called inert gases, they have complete outer electron shells and were believed not to react with other elements or compounds .
Why is argon unreactive?
Argon is unreactive because it has the maximum number of electrons in its outer shell .
