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.
Argon is a gas at STP.
In its natural form, argon is a gas, not a mineral!
According to wikipedia, argon has 24 known isotopes. 40Ar is most abundant at about 99.6% of natural argon.
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!
Argon is a gas in it's natural state. So, no, it would not make a good conductor of heat or electricity. In fact, it would be an excellent insulator because it is an inert gas. For this reason, it is used to fill incandescent light bulbs.
