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.
26 cze 2024 · Argon is a colorless, odorless, and tasteless noble gas with the chemical symbol Ar and atomic number 18. It’s the third most abundant gas in the Earth’s atmosphere and is known for its inertness, rarely participating in chemical reactions.
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].
Definition, mass & chemical names. Argon. Argon is a rare and inert gas and belong to the Nobel gases. It was discovered by Sir William Ramsay and Lord Rayleigh in 1894. It emits unique and sharp spectral lines and is widely used in high speed photography and lasers.
Argon is a chemical element; it has symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. [9] Argon is the third most abundant gas in Earth's atmosphere, at 0.934% (9340 ppmv).
Argon is the glowing gas that occupies some fluorescent tubes, and it is an insulating filler in some double-pane thermal windows. The principal isotope of argon is 40 Ar (99.6% abundance); it has two other stable isotopes, 36 Ar (0.3%) and 38 Ar (0.1%). Argon-40 is formed by β -decay of the long-lived potassium isotope 39 K.
