Where could Argon be found?

Where is argon found on Earth? Argon is the most abundant of the noble gases in the Earth's atmosphere. It constitutes nearly 1% (0.94%) of the volume of air making it the third most abundant element in air after nitrogen and oxygen. Argon is also found in small traces in the Earth's crust and ocean waters.

Where does argon in the atmosphere come from?

Argon is obtained from the air as a byproduct of the production of oxygen and nitrogen. Argon is frequently used when an inert atmosphere is needed. It is used to fill incandescent and fluorescent light bulbs to prevent oxygen from corroding the hot filament.

Where is argon used in everyday life?

It is used in this way for the production of titanium and other reactive elements. It is also used by welders to protect the weld area and in incandescent light bulbs to stop oxygen from corroding the filament. Argon is used in fluorescent tubes and low-energy light bulbs.

Is argon a renewable resource?

You can extract argon from air to do most of what helium is used for. It's completely inert and liquefies at 87K. Pure argon gas costs $5 a kilo. ... Helium is a renewable resource that leaks out of the Earth's crust and regenerates from solar wind constantly, contrary to op.

How do you make argon?

Argon is industrially extracted from liquid air in a cryogenic air separation unit by means of fractional distillation. When nitrogen gas present in the atmosphere is heated using hot calcium or magnesium, a nitride is formed leaving behind small amount of argon as an impurity.

How is argon used in scuba diving?

Argon serves as a better insulator than air. By filling the dry suit with argon the diver replaces the thinner, more compressible air with denser gas that does not compress nearly as much under a given pressure. This is a very advantageous concept for the dry suit diver.

Is argon toxic to humans?

A: Argon is an inert, non-toxic gas. It's denser than oxygen and present in 1 percent of the air we breathe. It's an extremely stable element with non-reactive properties.

How is liquid argon produced?

Argon is produced at air separation plants by liquefaction of atmospheric air and separation of the argon by continuous cryogenic distillation. The argon is then recovered as a cryogenic liquid. Argon is most commonly used in its gaseous state.

How is argon produced in the atmosphere?

In earth's atmosphere, Ar-39 is made by cosmic ray activity, primarily with Ar-40. In the subsurface environment, it is also produced through neutron-capture by K-39 or alpha emission by calcium. Argon-37 is produced from the decay of calcium-40, the result of subsurface nuclear explosions.

Why is there so much argon in the atmosphere?

One reason is because it is non-reactive. Like other noble gases, it is stable and resists combining with other elements. Once it gets in the atmosphere it is difficult to get rid of. Another reason it is found in the atmosphere is because it is relatively heavy.

What is argon gas used for in hospitals?

Medically used for argon gas knife, gas knife, and other surgical instruments. Compressed air is used to deliver power to oral surgical instruments, orthopedic instruments, and ventilators.

What are three uses for argon?

Argon provides an inert gas shield in welding and brazing, in lightbulbs and lasers, in Geiger counters, and in the production and fabrication of certain metals.

What is xenon used for in everyday life?

Uses of Xenon

Xenon is used in photographic flashes, in high pressure arc lamps for motion picture projection, and in high pressure arc lamps to produce ultraviolet light. It is used in instruments for radiation detection, e.g., neutron and X-ray counters and bubble chambers.

Why is argon so cheap?

Argon is inexpensive, since it occurs naturally in air and is readily obtained as a byproduct of cryogenic air separation in the production of liquid oxygen and liquid nitrogen: the primary constituents of air are used on a large industrial scale.

How much argon is in the atmosphere?

Earth's atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.
