Gallium does not occur as a free element in nature, but as gallium(III) compounds in trace amounts in zinc ores and in bauxite. It is also the most corrosion-resistant metal, even at temperatures as high as 2000 °C. Because of its closed-shell electron configuration, its density and melting and boiling points differ significantly from those of most other lanthanides.

It does not form a boride, silicide, or carbide, and the hydride InH3 has at best a transitory existence in ethereal solutions at low temperatures, being unstable enough to spontaneously polymerize without coordination. Knowledge of the electron configuration of different atoms is useful in understanding the structure of the periodic table of elements. Indium(III) oxide, In2O3, forms when indium metal is burned in air or when the hydroxide or nitrate is heated.

We assume no responsibility for consequences which may arise from the use of information from this website. These have similar chemical properties, but palladium has the lowest melting point and is the least dense of them. Palladium, platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs). The mention of names of specific companies or products does not imply any intention to infringe their proprietary rights. Thus, although thallium(III) is a moderately strong oxidizing agent, indium(III) is not, and many indium(I) compounds are powerful reducing agents.

Chromium is a steely-grey, lustrous, hard and brittle metal4 which takes a high polish, resists tarnishing, and has a high melting point. Iodine is the least abundant of the stable halogens, being the sixty-first most abundant element. All of the alkali metals have a single valence electron in the outer electron shell, which is easily removed to create an ion with a positive charge – a cation, which combines with anions to form salts. The chemical symbol for Xenon is Xe. This is an aspect that is often forgotten in the current debate, e.g. [75] Indium tin oxide and indium phosphide harm the pulmonary and immune systems, predominantly through ionic indium,[76] though hydrated indium oxide is more than forty times as toxic when injected, measured by the quantity of indium introduced.
