Echeverría, E. Cremades, F. Barragán, S. Alvarez, Dalton Trans. 2008, 21, 2832-2838. DOI:10.1039/b801115j PMID:18478144. 1 S 0.

2018年11月26日 · Five major uses of argon, for example, include its placement in neon lights, its ability to help determine the age of very old substances, its use as an insulator in manufacturing metals, its role as a welding gas and its use in 3-D printing.

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.

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, 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.

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].

2020年10月2日 · Argon is atomic number 18 on the periodic table, with the element symbol Ar. Here is a collection of useful and interesting argon element facts. Argon is a colorless, flavorless, odorless noble gas. Unlike some other gases, it remains colorless even in liquid and solid form. It is nonflammable and nontoxic.

2025年1月21日 · 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.
