What is special about rhenium?
Rhenium is a silvery-white metal with one of the highest melting points of all elements, exceeded by only tungsten and carbon. It also has one of the highest boiling points of all elements, and the highest among stable elements. It is also one of the densest, exceeded only by platinum, iridium and osmium.
What are three interesting facts about rhenium?
Interesting Facts About Rhenium
- Rhenium was named after a river in Germany. Rhenium was first discovered way back in 1925 by a trio of scientists named Otto Berg, Walter Noddack, and Ida Tacke Noddack.
- Rhenium has very high boiling and melting points.
- Rhenium is rarer than most other elements.
What is unique about mercury element?
Mercury looks pretty, in its shiny, fast-moving liquid form, but don’t touch! It can be extremely poisonous to humans. The symbol Hg that mercury is known by comes from its Greek name, hydrargyrum, which means “liquid silver” — to reflect its shiny surface. The element is also known as quicksilver for its mobility.
What happens if you touch mercury?
MERCURY EXPOSURE If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin, but not usually enough to harm you.

How did rhenium get its name?
The German discoverers called their element rhenium, after Rhenus, the Latin name for the river Rhine (pictured) that flows close to the place where they were working.
Where is rhenium most commonly found?
Commercial rhenium is obtained from molybdenum roaster-flue dusts found in copper-sulfide ores. However, rhenium does not occur freely in nature or as a compound in mineral ores. Molybdenum contains from 0.002 percent to 0.2 percent rhenium, and the element is found widely spread through the Earth’s crust.
Where is rhenium found naturally?
Rhenium does not occur free in nature or as a compound in a particular type of mineral. It is widely spread throughout Earth’s crust at approximately 1 to 4 ppb. Commercially, rhenium is obtained through the processing of copper-sulfide ores that contain molybdenum.
What is rhenium?
Rhenium is a rare silver-white metal and belongs to the 6th-period transition metal in the periodic table. It is one of the rarest elements in the earth’s crust and one of the highest melting and boiling elements. In today’s article, we will take a look at 6 interesting facts about rhenium.
What is the melting point of rhenium?
Rhenium is a silver-white metal. Its melting point is 3186℃, boiling point 5596℃, and density 20.53g/cm. The metal rhenium is very hard, resistant to wear and corrosion. Rhenium is insoluble in hydrochloric acid and soluble in nitric acid to generate Perrhenic acid: 3Re + 7HNO3 → 3HReO4 + 7NO + 2H2O.
What are 5 interesting facts about mercury?
Although people think of Mercury as a red planet, it actually has a dark gray exterior. Mercury is an estimated 57910000km away from the Sun. It has a radius of 2,440km. Almost 75% of this is made up from its core. A full day on Mercury is equal to 59 days on Earth! A full year on Mercury is only 88 days long.
How much rhenium is there in the world?
According to data released by the US geological survey in 2015, the world’s proven reserves of rhenium are about 1,100 tonnes, including about 500 tonnes in the US and 600 tonnes in other countries.
