Rhenium is a chemical element; it has symbol Re and atomic number 75. It is a silvery-gray, heavy, third-row transition metal in group 7 of the periodic table. With an estimated average concentration of 1 part per billion (ppb), rhenium is one of the rarest elements in the Earth's crust.

Rhenium (Re), chemical element, a very rare metal of Group 7 (VIIb) of the periodic table and one of the densest elements. Predicted by the Russian chemist Dmitry Ivanovich Mendeleyev (1869) as chemically related to manganese, rhenium was …

Rhenium is element 75 in the periodic table and in many ways a rather unusual element. It is one of the rarest elements on the Earth with an abundance of something like 1 part per million. It is also one of the densest elements, following only platinum, iridium and osmium and it is one of the highest melting point elements exceeded only by ...

Rhenium is a greyish silver metal. Rhenium has remarkably high boiling point (5627 °C) and is categorized as the element with the highest boiling point. It also has one of the highest melting point (3170 °C), second only to carbon and tungsten. Rhenium is a …

2024年10月5日 · Rhenium (symbol Re and atomic number 75) is a dense silvery transition metal. It is one of the rarest metals and has the second highest melting point, after tungsten. Rhenium is important in jet engines, catalysts, and cancer therapies. Here is a …

Rhenium. Rhenium is a chemical element with symbol Re and atomic number 75. Classified as a transition metal, Rhenium is a solid at room temperature.

What is Rhenium. A rare earth metal, rhenium (pronounced as REE-nee-em) belongs to the family of transition metals denoted by the chemical symbol Re [1]. It has 33 isotopes with known half-lives, their mass numbers ranging from 160 to 192.

Rhenium (Re), the last naturally-occurring element to be discovered, was discovered in Germany in 1925. The process was so complicated and the cost so high that production was discontinued until early 1950 when tungsten-rhenium and molybdenum-rhenium alloys were prepared.

Rhenium is a rare, silvery-white, lustrous, dense metal. It resists corrosion and oxidation but slowly tarnishes in moist air. Of the elements, only carbon and tungsten have higher melting points and only iridium, osmium, and platinum are more dense.
