indium (In), chemical element, rare metal of main Group 13 (IIIa, or boron group) of the periodic table. Indium has a brilliant silvery-white lustre. It was discovered (1863) by German chemists Ferdinand Reich and Hieronymus Theodor Richter while they were examining zinc ore samples.
What is indium on the periodic table?
Indium is a chemical element with the symbol In and atomic number 49. 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 color is indium?
silvery white
Indium is a soft, ductile, manleable, lustrous metallic metal. Its colour is silvery white and it has a face-centered tetragonal structure. It is liquid over a wide range of temperatures, like gallium that belongs to its same group.

Where do you find indium?
Source & abundance Indium is rarely found uncombined in nature and is typically found in zinc, iron, lead and copper ores. It is the 61st most common element in the Earth’s crust and around three times more abundant than silver or mercury, according to the U.S. Geological Survey (USGS).
Is indium a metalloid?
Boron is also the only metalloid in this group. The other four elements in the group—aluminum (Al), gallium (Ga), indium (In), and thallium (Tl)—are all metals. Group 13 elements have three valence electrons and are fairly reactive. Boron is a very hard, black metalloid with a high melting point.
Why is the chemical element indium named so?
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. They named the new element indium, after the Latin word indicum, meaning violet.
What metal is heaviest?
osmium
The Heaviest Metal. The heaviest metal is osmium, which has, bulk for bulk, nearly twice the weight of lead. The specific gravity of gold is about 19 1/4, while that of osmium is almost 22 1/2.
What does indium look like?
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. Its estimated abundance in the Earth’s crust is 0.1 parts per million (ppm) — a little more abundant than silver or mercury, according to the Royal Society of Chemistry.
