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. [10] Argon is the third most abundant gas in Earth's atmosphere, at 0.934% (9340 ppmv).

Argon is a colourless, odourless gas that is totally inert to other substances. Argon is often used when an inert atmosphere is needed. It is used in this way for the production of titanium and other reactive elements. It is also used by welders to protect the weld area and in incandescent light bulbs to stop oxygen from corroding the filament.

2025年2月26日 · Argon, chemical element, inert gas of Group 18 (noble gases) of the periodic table, terrestrially the most abundant and industrially the most frequently used of the noble gases. It is used in gas-filled electric light bulbs, radio tubes, and Geiger counters.

Argon is used in situations where materials need to be protected from oxygen or other gases. A good example is an incandescent lightbulb, which consists of a metal wire inside a clear glass bulb. An electric current passes through the wire, causing it to get very hot and give off light.

Argon is a chemical element with symbol Ar and atomic number 18. Classified as a noble gas, Argon is a gas at room temperature. [Ne]3s 2 3p 6. B. Cordero, V. Gómez, A.E. Platero-Prats, M. Revés, J. Echeverría, E. Cremades, F. Barragán, S. Alvarez, Dalton Trans. 2008, 21, 2832-2838. DOI:10.1039/b801115j PMID:18478144. 1 S 0.

2023年6月26日 · Key Takeaways: Is argon a metal or nonmetal? Argon is classified as a nonmetal because it lacks the typical physical and chemical properties of metals and shares characteristics with other elements in the nonmetal group of the periodic table.

2024年5月31日 · Argon is neither a semimetal nor a metal. It is a noble gas with a full valence electron shell, making it chemically inert and non-metallic in nature.

2024年5月23日 · Is argon a metal? No, argon is not a metal. It is a noble gas and is classified as a nonmetal in the periodic table of elements. Argon is colorless, odorless, and inert under normal...
