Argont

Argont is a chemical element with the symbol Ar and atomic number 18. It is a noble gas, which means it is inert and does not readily form compounds with other elements. Argont is the third most abundant gas in the Earth's atmosphere, making up approximately 0.934% of the air. It is colorless, odorless, and tasteless, and it is non-toxic in its elemental state. Argont is used in various applications, including as a protective gas in welding and metalworking, as a coolant in nuclear reactors, and as a filling gas in incandescent and fluorescent lights. Its inert nature makes it ideal for these uses, as it does not react with other substances. Argont was discovered in 1894 by the Scottish chemist Sir William Ramsay and the English chemist Lord Rayleigh. The name "argont" comes from the Greek word "argos," which means "inactive," reflecting the element's chemical inertness.
