Osmium has the highest melting point and the lowest vapor pressure of any of the platinum group of metals it is also the densest naturally ocurring element. This table has links to all the properties of osmium included within WebElements.

tanker trucks. Titanium condenser tubes are usually the best technical choice, however titanium is very expensive material. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Lutetium is the last element in the lanthanide series, and it is traditionally counted among the rare earths. Rhenium compounds may be irritating to the eyes and respiratory tract.Subacute to chronic toxicity:No effects known.Subacute to chronic toxicity:Boron affects the central nervous system. See also: Atomic Number – Does it conserve in a nuclear reaction? Its density is 22.5 grams per cubic centimeter. Osmium is unworkable as a metal. Calculations of density from the X-ray diffraction data may produce the most reliable data for these elements, giving a value of 22.587±0.009 g/cm for osmium, slightly denser than the 22.562±0.009 g/cm of iridium; both metals are nearly 23 times as dense as water, and ​1 ⁄6 times as dense as gold.

The chemical symbol for Tantalum is Ta. The configuration of these electrons follows from the principles of quantum mechanics. Zirconium is widely used as a cladding for nuclear reactor fuels.

), and shape. Bromine is a chemical element with atomic number 35 which means there are 35 protons and 35 electrons in the atomic structure.

Thorium metal is silvery and tarnishes black when exposed to air, forming the dioxide. The chemical symbol for Terbium is Tb. The chemical symbol for Americium is Am. Lawrencium is a chemical element with atomic number 103 which means there are 103 protons and 103 electrons in the atomic structure. Link to definition of property Link to osmium data for property; Abundances of the elements: osmium: Abundance in carbonaceous meteorites (by weight) osmium The chemical symbol for Zirconium is Zr.

This dependence is usually expressed by the coefficient of linear or volume expansion. Boron has an energy band gap of 1.50 to 1.56 eV, which is higher than that of either silicon or germanium.

COPYRIGHT 1997-2016 AMERICAN ELEMENTS. Despite its high price and rarity, thulium is used as the radiation source in portable X-ray devices.

The chemical symbol for Holmium is Ho. A gray-white metal, osmium is very hard, brittle, and difficult to work, even at high temperatures. For example, carbon has nine possible integer oxidation states from −4 to +4. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal.

For example, water boils at 100°C (212°F) at sea level, but at 93.4°C (200.1°F) at 1900 metres (6,233 ft) altitude. Praseodymium is a soft, silvery, malleable and ductile metal, valued for its magnetic, electrical, chemical, and optical properties.

Argon is the third-most abundant gas in the Earth’s atmosphere, at 0.934% (9340 ppmv).

The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table.

Osmium is a hard, brittle, bluish-white transition metal in the platinum group that is found as a trace element in alloys, mostly in platinum ores.

Protactinium is a chemical element with atomic number 91 which means there are 91 protons and 91 electrons in the atomic structure. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins.

Zirconium is a lustrous, grey-white, strong transition metal that resembles hafnium and, to a lesser extent, titanium. Atomic mass. The melting point of ice is 0 °C.
Actinium is a soft, silvery-white radioactive metal.

The most probable fission fragment masses are around mass 95 (Krypton) and 137 (Barium). Bismuth is a brittle metal with a silvery white color when freshly produced, but surface oxidation can give it a pink tinge.

Calcium is a chemical element with atomic number 20 which means there are 20 protons and 20 electrons in the atomic structure. Holmium is a relatively soft and malleable silvery-white metal. Uranium is weakly radioactive because all isotopes of uranium are unstable, with half-lives varying between 159,200 years and 4.5 billion years. Redox Tuning in Crystalline and Electronic Structure of Bimetal-Organic Frameworks Derived Cobalt/Nickel Boride/Sulfide for Boosted Faradaic Capacitance. Shipping documentation includes a Certificate of Analysis and Safety Data Sheet (SDS). The chemical symbol for Actinium is Ac. The elemental metal is rarely found in nature, but once isolated artificially, the formation of an oxide layer (passivation) stabilizes the free metal somewhat against further oxidation.
