Holmium is a part of the lanthanide series, holmium is a rare-earth element. The chemical symbol for Rubidium is Rb. [53] The compound semiconductors InGaN and InGaP are used in light-emitting diodes (LEDs) and laser diodes. Significant concentrations of boron occur on the Earth in compounds known as the borate minerals. Terbium is a silvery-white, rare earth metal that is malleable, ductile, and soft enough to be cut with a knife. Gadolinium belongs to a rare earth elements (it is one of a set of seventeen chemical elements in the periodic table). Technetium is the lightest element whose isotopes are all radioactive; none are stable. The chemical symbol for Molybdenum is Mo. Platinum is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Cerium is a soft, ductile and silvery-white metal that tarnishes when exposed to air, and it is soft enough to be cut with a knife. Radon is a radioactive, colorless, odorless, tasteless noble gas. Lead has the highest atomic number of any stable element and concludes three major decay chains of heavier elements. We use cookies to ensure that we give you the best experience on our website.

Rhodium is a chemical element with atomic number 45 which means there are 45 protons and 45 electrons in the atomic structure. Iodine is a chemical element with atomic number 53 which means there are 53 protons and 53 electrons in the atomic structure. Chlorination, bromination, and iodination of In produce colorless InCl3, InBr3, and yellow InI3. Beryllium is a hard, grayish metal naturally found in mineral rocks, coal, soil, and volcanic dust. By 1992, the thin-film application had become the largest end use. Like tin, a high-pitched cry is heard when indium is bent – a crackling sound due to crystal twinning. Gold is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Titanium can be used in surface condensers. [69] Indium is added to some dental amalgam alloys to decrease the surface tension of the mercury and allow for less mercury and easier amalgamation. Note that when writing the electron configuration for an atom like Fe, the 3d is usually written before the 4s. Indium is a silvery-white, highly ductile post-transition metal with a bright luster. Like all alkali metals, lithium is highly reactive and flammable, and is stored in mineral oil. Naturally occurring potassium is composed of three isotopes, of which 40K is radioactive. Hassium: Value is a guess based on periodic table trend. [22], Less frequently, indium forms compounds in oxidation state +2 and even fractional oxidation states. Our Website follows all legal requirements to protect your privacy. Tellurium is a brittle, mildly toxic, rare, silver-white metalloid. The chemical symbol for Oxygen is O. Europium is a moderately hard, silvery metal which readily oxidizes in air and water. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. The chemical symbol for Gallium is Ga. Gallium has similarities to the other metals of the group, aluminium, indium, and thallium. 2) You may not distribute or commercially exploit the content, especially on another website. [67] Indium is an ingredient in the gallium–indium–tin alloy galinstan, which is liquid at room temperature and replaces mercury in some thermometers. This explains why the radioactive isotope is more abundant than the stable one. Thus, you should write the electron configuration for 10 electrons. Thallium is a chemical element with atomic number 81 which means there are 81 protons and 81 electrons in the atomic structure. The chemical symbol for Gold is Au. Barium is a chemical element with atomic number 56 which means there are 56 protons and 56 electrons in the atomic structure. www.nuclear-power.net. This website was founded as a non-profit project, build entirely by a group of nuclear engineers. The chemical symbol for Yttrium is Y. Yttrium is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a “rare-earth element”. It is also the most corrosion-resistant metal, even at temperatures as high as 2000 °C. Bismuth is a chemical element with atomic number 83 which means there are 83 protons and 83 electrons in the atomic structure. When an electron is added to a neutral atom, energy is released.

The name xenon for this gas comes from the Greek word ξένον [xenon], neuter singular form of ξένος [xenos], meaning ‘foreign(er)’, ‘strange(r)’, or ‘guest’. [53], Indium wire is used as a vacuum seal and a thermal conductor in cryogenics and ultra-high-vacuum applications, in such manufacturing applications as gaskets that deform to fill gaps.
