ARGON

* BASIC FACTS*

Element Name: Argon Element Symbol: Ar Atomic Number: 18 Group Name: Noble Gas

*INTERESTING INFORMATION*

*Argon is colorless and odorless.

*It is very inert and is not known to form true chemical compounds.

*It makes a good atmosphere for working with air-sensitive materials since it is heavier than air and less reactive that Nitrogen.

*Argon is present to a small extent in the Earth's atmosphere and is obtained as a byproduct from the liquefaction and separation of air.

*Its presence in air was suspected by Cavendish in 1785, discovered by Lord Rayleigh and Sir William Ramsay in 1894.

*USES OF ARGON*

* Argon is used in electrical light bulbs, fluorescent tubes, photo tubes, and glow tubes at a pressure of about 3 mm.

*Argon is used as a motionless gas shield for arc welding and cutting.

*Argon can serve as a blanket for the production of titanium and other reactive elements.

*Argon provides a prospective atmosphere for growing silicon and germanium crystals.

Argon's light makes me think.

How does it properties form fluorescent lights?

That energize dances on wild nights!

Argon has protons.

Eighteen to be exact!

And neutrons are present.

Twenty two, that's a fact!

Argon is really not cool at all

But to get an "A" from Mrs. Bova, I'd fly and I'd crawl!
