Is indium a pure substance or mixture?
Natural indium is a mixture of two isotopes: indium-113 (4.28 percent) and indium-115 (95.72 percent). The periodic table is made up of 118 elements.
What form is indium found in?
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).
In what compounds or forms is indium commonly found?
Indium is one of the least abundant minerals on Earth. It has been found uncombined in nature, but typically it is found associated with zinc minerals and iron, lead and copper ores.
What is a indium compound?
Indium compounds are chemical compounds that contain the chemical element indium.
Is indium a compound?
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.
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.
Is indium paramagnetic or diamagnetic?
Magnetic Type of the elements
| Hydrogen | Diamagnetic | Niobium |
|---|---|---|
| Fluorine | N/A | Indium |
| Neon | Diamagnetic | Tin |
| Sodium | Paramagnetic | Antimony |
| Magnesium | Paramagnetic | Tellurium |
What elements does indium bond with?
Indium metal dissolves in acids, but does not react with oxygen at room temperature. At higher temperatures, it combines with oxygen to form indium oxide (In 2 O 3 ).

Is indium chloride ionic or covalent?
About Indium(II) Chloride They are formed through various chlorination processes whereby at least one chlorine anion (Cl-) is covalently bonded to the relevant metal or cation.
Is indium a mineral?
Amy C. Tolcin, a mineral commodity specialist for the U.S. Geological Survey, compiled the following information on indium, a minor metal that is important in flat-panel displays. Geologically, the occurrence of indium minerals is rare.
Is n2 diamagnetic or paramagnetic?
O₂ is paramagnetic because there are more unpaired electrons and N₂ is diamagnetic because there are no unpaired electrons. The number of unpaired electrons in O2 is 2, hence it is paramagnetic.
How is indium used as a chemical element?
Indium is obtained in its pure form by separating it from zinc and other elements in zinc ores. The primary use of indium is in making alloys. An alloy is made by melting and mixing two or more metals. The mixture has properties different from those of the individual metals.
What kind of semiconductors are made of indium?
High-purity indium (99.9999 and 99.99999) is used in III-V compound semiconductors such as laser diodes. The Indium Corporation is confident of the sustained indium metal supply. There has been concern expressed that the world may face an indium shortage given the rising price environment experienced this year.
Are there any isotopes of the element indium?
Two naturally occurring isotopes of indium exist, indium-113 and indium-115. Isotopes are two or more forms of an element.
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).
