Where was argon discovered what country?
Argon was first isolated in 1785 in Clapham, South London, by Henry Cavendish.
Who was argon discovered by?
William Ramsay
John William Strutt, 3rd Baron Rayleigh

Where did the argon 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.
Who discovered argon and in which year?
Argon was discovered by a Scottish chemist, Sir William Ramsay and an English chemist, Lord Rayleigh in 1894. However, an English scientist, Henry Cavendish identified the presence of argon 200 years before its discovery when he found a small amount of gas left behind while separating nitrogen and oxygen from air.
Where is argon on the periodic table?
Group 18
argon (Ar), chemical element, inert gas of Group 18 (noble gases) of the periodic table, terrestrially the most abundant and industrially the most frequently used of the noble gases.
When was the element xenon discovered?
1898Xenon / Discovered
Xenon was discovered in July 1898 by William Ramsay and Morris Travers at University College London. They had already extracted neon, argon, and krypton from liquid air, and wondered if it contained other gases.

What is argon in?
Almost all of the argon found in the atmosphere is radiogenic argon-40 and, in space, the most common argon isotope is argon-36. Most commonly, argon is one of the elements used in the welding industry as it provides an inert atmosphere in which welded metals will not oxidise.
What country discovered xenon?
England
Xenon was discovered in England by the Scottish chemist William Ramsay and English chemist Morris Travers in September 1898, shortly after their discovery of the elements krypton and neon.
Who first discovered xenon?
Why is argon the cheapest noble gas?
Why is argon the cheapest noble gas? 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.
Where is argon found naturally?
Argon is isolated from air by fractionation, most commonly by cryogenic fractional distillation, a process that also produces purified nitrogen, oxygen, neon, krypton and xenon. The Earth’s crust and seawater contain 1.2 ppm and 0.45 ppm of argon, respectively. Ar (0.06%). Naturally occurring 40 Ca (88.8%) by beta decay.
When did William Ramsay discovered argon?
They subsequently worked in their separate laboratories on this problem but communicated the results of their labours almost daily. At the meeting of the British Association in August 1894, they announced the discovery of argon. While seeking sources of argon in the mineral kingdom, Ramsay discovered helium in 1895.
Is argon heavier than air?
No, as other posters have mentioned argon is only 38% heavier than air. Think about an oil/water mixture…Olive oil is about 10% lighter than water. It will separate from the water, but slowly and only if held still, definitely not in a turbulent environment similar to lung function.
