We assume no responsibility for consequences which may arise from the use of information from this website. Liquid nitrogen (made by distilling liquid air) boils at 77.4 kelvins (−195.8°C) and is used as a coolant. In general, melting is a phase change of a substance from the solid to the liquid phase. Chemically, indium is similar to gallium and thallium. agreement. Zirconium is widely used as a cladding for nuclear reactor fuels. Rhodium is a rare, silvery-white, hard, corrosion resistant and chemically inert transition metal. Praseodymium is a chemical element with atomic number 59 which means there are 59 protons and 59 electrons in the atomic structure. At the melting point the two phases of a substance, liquid and vapor, have identical free energies and therefore are equally likely to exist. Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! Pure germanium is a semiconductor with an appearance similar to elemental silicon. Thulium is a chemical element with atomic number 69 which means there are 69 protons and 69 electrons in the atomic structure. The most commonly used spontaneous fission neutron source is the radioactive isotope californium-252. Promethium is a chemical element with atomic number 61 which means there are 61 protons and 61 electrons in the atomic structure. In nuclear reactors, promethium equilibrium exists in power operation. These elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth elements. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Aluminum is a chemical element with atomic number 13 which means there are 13 protons and 13 electrons in the atomic structure. Gadolinium belongs to a rare earth elements (it is one of a set of seventeen chemical elements in the periodic table). Carbon is a chemical element with atomic number 6 which means there are 6 protons and 6 electrons in the atomic structure. Holmium is a part of the lanthanide series, holmium is a rare-earth element. Thulium is an easily workable metal with a bright silvery-gray luster. The chemical symbol for Phosphorus is P. As an element, phosphorus exists in two major forms—white phosphorus and red phosphorus—but because it is highly reactive, phosphorus is never found as a free element on Earth.    Crystal Structure, Element Groups: Calcium is an alkaline earth metal, it is a reactive pale yellow metal that forms a dark oxide-nitride layer when exposed to air. Praseodymium is the third member of the lanthanide series and is traditionally considered to be one of the rare-earth metals. The chemical properties of this silvery gray, crystalline transition metal are intermediate between rhenium and manganese. The chemical symbol for Dysprosium is Dy. Our Website follows all legal requirements to protect your privacy. Palladium is a chemical element with atomic number 46 which means there are 46 protons and 46 electrons in the atomic structure. The first alloy used on a large scale was bronze, made of tin and copper, from as early as 3000 BC. Aluminium is a silvery-white, soft, nonmagnetic, ductile metal in the boron group. It is the heaviest element that can be formed by neutron bombardment of lighter elements, and hence the last element that can be prepared in macroscopic quantities. Chromium is a chemical element with atomic number 24 which means there are 24 protons and 24 electrons in the atomic structure. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Silver is a soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. The metal is found in the Earth’s crust in the pure, free elemental form (“native silver”), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Lawrencium is the final member of the actinide series. Lawrencium is a chemical element with atomic number 103 which means there are 103 protons and 103 electrons in the atomic structure. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels. The chemical symbol for Silicon is Si. It is one of the least reactive chemical elements and is solid under standard conditions. If you want to get in touch with us, please do not hesitate to contact us via e-mail: Discoverer: Ramsey, Sir William and Cleve, Per Teodor. All of its isotopes are radioactive. Iron is a metal in the first transition series. Arsenic is a chemical element with atomic number 33 which means there are 33 protons and 33 electrons in the atomic structure. Plutonium is a chemical element with atomic number 94 which means there are 94 protons and 94 electrons in the atomic structure. Lead is widely used as a gamma shield. The chemical symbol for Hafnium is Hf. Uranium is weakly radioactive because all isotopes of uranium are unstable, with half-lives varying between 159,200 years and 4.5 billion years. Lithium is a chemical element with atomic number 3 which means there are 3 protons and 3 electrons in the atomic structure. Chemically, sulfur reacts with all elements except for gold, platinum, iridium, tellurium, and the noble gases. In nuclear industry, especially natural and artificial samarium 149 has an important impact on the operation of a nuclear reactor. As the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine. Oxygen is a colourless, odourless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air.
