Argon is a chemical element with symbol Ar and atomic number 18. It is in group 18 (noble gases) of the Periodic Table. Argon is the third most common gas in the Earth's atmosphere, at 0.93% (9,300 ppm), making it approximately 23.8 times as abundant as next most common atmospheric gas, carbon dioxide (390 ppm), and more than 500 times as abundant as the next most common noble gas, neon (18 ppm). Nearly all of this argon is radiogenic argon-40 derived from the decay of potassium-40 in the Earth's crust. In the universe, argon-36 is by far the most common argon isotope, being the preferred argon isotope produced by stellar nucleosynthesis in supernovas.
The name "argon" is derived from the Greek word αργον meaning "lazy" or "the inactive one", a reference to the fact that the element undergoes almost no chemical reactions. The complete octet (eight electrons) in the outer atomic shell makes argon stable and resistant to bonding with other elements. Its triple point temperature of 83.8058 K is a defining fixed point in the International Temperature Scale of 1990.
Argon is produced industrially by the fractional distillation of liquid air. Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily non-reactive substances become reactive; for example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. Argon gas also has uses in incandescent and fluorescent lighting, and other types of gas discharge tubes. Argon makes a distinctive blue-green gas laser.
What else can I help you with?
What was the element Argon natural state?
Argon is a gas at STP.
Which of argon's three isotopes is most abundant in nature argon-36 argon-38 or argon-40?
According to wikipedia, argon has 24 known isotopes. 40Ar is most abundant at about 99.6% of natural argon.
Is argon natural or synthetic?
Argon is a naturally occurring element.It is not chemically reactive and is heavier than air - so your argon balloons will sit on the floor not the ceiling!
How is argon used in its Natural mineral?
Argon is a noble gas and does not react with other elements, so it does not typically participate in mineral formations. Instead, argon is commonly found in the Earth's atmosphere in small amounts, where it acts as an inert gas.
Which isotope of argon is must common?
Argon-40 is the most common isotope of argon, making up about 99.6% of natural argon. It is formed by the radioactive decay of potassium-40 in rocks.
What was the element Argon natural state?
Argon is a gas at STP.
What does argon look like in its natural state?
It is a colourless gas.
Is argon is monoatomic or diatomic?
Argon is a monoatomic gas, meaning it exists as individual atoms in its natural state.
Does argon have colour?
Argon is a colorless and odorless gas. It is a noble gas that does not typically exhibit color in its natural state.
What is the ion formula for argon?
Argon is a noble gas and exists as a monoatomic molecule in its natural state, which means it does not typically form ions. Its chemical symbol is Ar.
Is argon a man made or natural element?
Argon is a natural element found in the air.
Is argon sinthetic or natural?
natural
What does Argon consist of?
Argon is a chemical element with the symbol Ar and atomic number 18. It is a noble gas that is colorless, odorless, and tasteless. In its natural state, argon is a monatomic gas present in Earth's atmosphere at a concentration of about 0.934%.
Formula of compound argon?
Not formula but the chemical symbol for argon: Ar. Also argon is not a compound but a chemical element.
Can argon change color?
When excited by electric current flowing in it.
What in the world has argon in it?
It is mainly the atmosphere. Compounds of argon are not natural on earth.
How many bonds does argon have?
Argon is a noble gas and therefore does not typically form bonds with other elements, as its electron configuration is stable with a full valence shell. It exists as single atoms in its natural state.
