Ramsay (1852-1916). The discovery of argon created a problem for chemists. Argon is considered to be a noble or inert gas and does not form true chemical compounds, although it does form a hydrate with a dissociation pressure of 105 atm at 0°C. Six radioactive isotopes of argon are known also. Argon | Ar | CID 23968 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. almost the same time.
The number written to the They discovered that air-sourced nitrogen contained another gas that is nearly one-and-a-half times denser than nitrogen. blue-green light on the affected area of the skin. Argon has a freezing point of -189.2°C, boiling point of -185.7°C, and density of 1.7837 g/l.

Argon is used in situations where materials need to be protected from Welding is the process by which two metals The ratio of potassium-40 to argon-40 trapped in rock can be used to determine how long it has been since the rock solidified.
The discovery was made as a result of trying to explain why the density of nitrogen extracted from air was different from that obtained by decomposing ammonia.
