22 kwi 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 (pronunciation: AR-gon) is a colorless, odorless, inert element belonging to the group of inert gases in the periodic table and is represented by the chemical symbol Ar [1, 2, 3].
Argon is a chemical element; it has symbol Ar and atomic number 18. It is mostly used as an inert shielding gas in welding and other high-temperature industrial processes. It is also used in incandescent, fluorescent lighting, and other gas-discharge tubes.
31 gru 2007 · Most argon is used in the production of steel where it is blown through the molten iron, along with oxygen. The argon does the stirring while the oxygen removes carbon as carbon dioxide. Argon is also used to exclude air to prevent oxidation of hot metals, in welding aluminium and in the production of titanium.
Argon (Ar) is a chemical element with atomic number 18. It belongs to a group of elements called noble gases. Making up roughly 1% of the Earth's atmosphere, argon must be considered a fairly abundant gas. There is more than twenty times more argon than carbon dioxide (CO 2) in our air.
