Why is indium called that?

Indium is named after the bright indigo line in its spectrum. The Japanese discovered that cotton was a difficult fabric to dye, except with indigo. So, indigo dye was widely used to colour cotton throughout the Edo period (1603–1867). A soft, silvery metal that is stable in air and water.

What is iodine named after?

Origin of the name The name is derived from the Greek ‘iodes’ meaning violet.

What is rubidium named after?

Rubidium was discovered (1861) spectroscopically by German scientists Robert Bunsen and Gustav Kirchhoff and named after the two prominent red lines of its spectrum. Rubidium and cesium often occur together in nature.

Where does indium originate?

Indium produced in idustry comes as the by-product of smelting zinc and lead sulfide ores, some of which can contain 1% indium. Specimens of uncombined indium metal have been found in a region of Russia and an indium mineral, indite, has been found in Siberia, but it is rare.

Is indium named after India?

They named the element indium, from the indigo color seen in its spectrum, after the Latin indicum, meaning ‘of India’.

Who discovered indium?

Ferdinand Reich
Indium/Discoverers

Indium, a soft malleable metal, was discovered in 1863 by two German chemists, Ferdinand Reich and Hieronymous Richter. Indium, named for the indigo blue line in its bright line spectrum, is primarily used in thin film indium tin oxide coatings for flat panel liquid crystal displays (LCDs).

How did the element titanium get its name?

Titanium is a transition metal that was discovered in 1791 by William Gregor. The name “titanium” originates from Greek Mythology, named after the sons of the Earth Goddess, known as the ‘Titans’.

What are some interesting facts about indium?

Indium is a lustrous silvery metal that is so soft and malleable it can be scratched with a fingernail and bent into nearly any shape. In nature, indium is quite rare and nearly always found as a trace element in other minerals — particularly in zinc and lead — from which it is typically obtained as a byproduct.

Is indium a metal?

Indium is the softest metal that is not an alkali metal. It is a silvery-white metal that resembles tin in appearance. It is a post-transition metal that makes up 0.21 parts per million of the Earth’s crust.

What are the physical properties of indium?

Physical properties. Indium is a silvery-white, shiny metal with a density of 7.31 grams per cubic centimeter. It is one of the softest metals known, even softer than lead. If drawn across a piece of paper, it leaves a mark like a “lead” pencil (which is actually carbon).

Where was indium discovered?

Indium was discovered in 1863 by the German chemist Ferdinand Reich at the Freiberg School of Mines in Germany. Reich was studying a sample of a zinc mineral blend that he thought might contain the recently discovered element thallium .
