argon, Chemical element, chemical symbol Ar, atomic number 18. Colourless, odourless, and tasteless, it is the most abundant of the noble gas es on Earth and the one most used in industry. It constitutes about 1% of air and is obtained by distillation of liquid air.
Oct 17, 2018 · Argon was discovered by Sir William Ramsay and Lord Rayleigh in 1894 (Scotland). Prior to the discovery, Henry Cavendish (1785) suspected some unreactive gas occurred in air. Ramsay and Rayleigh isolated argon by removing the nitrogen, oxygen, water, and carbon dioxide.
Apr 22, 2024 · Argon is a chemical element with the symbol Ar and atomic number 18. It is a colorless, odorless, tasteless, and non-toxic gas that is a member of the noble gases group in the periodic table. Argon is the third most abundant gas in the atmosphere, after nitrogen and oxygen.
Argon is the 18th element in the periodic table and has a symbol of Ar and atomic number of 18. It has an atomic weight of 39.948 and a mass number of 40. Argon has eighteen protons and twenty-two neutrons in its nucleus, and eighteen electrons in three shells.
Argon is gotten industrially by the fractional distillation of liquid air. About 700,000 tonnes of argon are produced worldwide every year. [11] [10] 40 Ar is made by the decay of 40 K with a half-life of 1.25 billion years by electron capture or positron emission.
