Boiling point. In 1925 they reported that they had detected the element in platinum ore and in the mineral columbite. Salts of [Re2Cl8]2− feature a quadruple metal-metal bond. Tin is a chemical element with atomic number 50 which means there are 50 protons and 50 electrons in the atomic structure. The high-temperature stability is also improved. Like all alkali metals, lithium is highly reactive and flammable, and is stored in mineral oil. Soluble salts, such as the rhenium halides or perrhenates, could be hazardous due to elements other than rhenium or due to rhenium itself. Note that, these points are associated with the standard atmospheric pressure. Name: Rhenium Symbol: Re Atomic Number: 75 Atomic Mass: 186.207 amu Melting Point: 3180.0 °C (3453.15 K, 5756.0 °F) Boiling Point: 5627.0 °C (5900.15 K, 10160.6 °F) Number of Protons/Electrons: 75 Number of Neutrons: 111 Classification: Transition Metal Crystal Structure: Hexagonal Density @ 293 K: 21.02 g/cm 3 Color: silverish Atomic Structure [44] In 2006, 77% of the rhenium consumption in the United States was in alloys. In general, boiling is a phase change of a substance from the liquid to the gas phase. The chemical symbol for Thulium is Tm. Adding a heat will convert the solid into a liquid with no temperature change. The temperature at which vaporization (boiling) starts to occur for a given pressure is called the saturation temperature or boiling point. The element is mainly used as a petroleum reforming catalyst and also in the turbine engine of high-temperature components as superalloys. [10] The symbol Np was later used for the element neptunium, and the name "nihonium", also named after Japan, along with symbol Nh, was later used for element 113. Rhenium is a chemical element with atomic number 75 which means there are 75 protons and 75 electrons in the atomic structure. Both the boiling points of rhenium and tungsten exceed 5000 K at standard pressure. melting point: 3,180 °C (5,756 °F) boiling point: 5,627 °C (10,161 °F) specific gravity: 20.5 at 20 °C (68 °F) oxidation states +1, +2, +3, +4, +5, +6, +7: electron configuration [Xe]4f 14 5d 5 6s 2 Francium is an alkali metal, that has one valence electron. Titanium is a lustrous transition metal with a silver color, low density, and high strength. Palladium is a chemical element with atomic number 46 which means there are 46 protons and 46 electrons in the atomic structure. Therefore, rhenium filaments exhibit a higher stability if the filament is operated not in vacuum, but in oxygen-containing atmosphere. [71], "Nipponium" redirects here.

The chemical symbol for Iodine is I. Iodine is the heaviest of the stable halogens, it exists as a lustrous, purple-black metallic solid at standard conditions that sublimes readily to form a violet gas. Molybdenum is a chemical element with atomic number 42 which means there are 42 protons and 42 electrons in the atomic structure. Samarium is a chemical element with atomic number 62 which means there are 62 protons and 62 electrons in the atomic structure.

Lead is soft and malleable, and has a relatively low melting point. [42][43] The metal form is prepared by reducing ammonium perrhenate with hydrogen at high temperatures:[25], Rhenium is added to high-temperature superalloys that are used to make jet engine parts, using 70% of the worldwide rhenium production. Mercury is a heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure. Berkelium is a member of the actinide and transuranium element series. It is used in the hydrogenation of fine chemicals and also as an additive to molybdenum and tungsten-based alloys. The chemical symbol for Thorium is Th. Who discovered it? The second-most important use is as a catalyst: rhenium is an excellent catalyst for hydrogenation and isomerization, and is used for example in catalytic reforming of naphtha for use in gasoline (rheniforming process). As the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.

In 4th- and 5th-generation superalloys, ruthenium is used to avoid this effect. Cerium is a chemical element with atomic number 58 which means there are 58 protons and 58 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. The most common rhenium chlorides are ReCl6, ReCl5, ReCl4, and ReCl3. Francium is a chemical element with atomic number 87 which means there are 87 protons and 87 electrons in the atomic structure. They both have similar penetration depth in tissue (5 mm for 186Re and 11 mm for 188Re), but 186Re has advantage of longer lifetime (90 hours vs. 17 hours). The chemical symbol for Fluorine is F. Fluorine is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. [11], Rhenium is generally considered to have been discovered by Walter Noddack, Ida Noddack, and Otto Berg in Germany. The available energy for this beta decay (2.6 keV) is one of the lowest known among all radionuclides. He realised from lines in its atomic spectrum that it contained an unknown element. The alloys normally contain 3% or 6% of rhenium.

This procedure yields a compact solid having a density above 90% of the density of the metal. In nuclear industry boron is commonly used as a neutron absorber due to the high neutron cross-section of isotope 10B.

The chemical symbol for Strontium is Sr. Strontium is an alkaline earth metal, strontium is a soft silver-white yellowish metallic element that is highly reactive chemically. Vanderwaals radius . The chemical symbol for Americium is Am. Chlorine is a chemical element with atomic number 17 which means there are 17 protons and 17 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). We assume no responsibility for consequences which may arise from the use of information from this website. The red rhenium trioxide ReO3 adopts a perovskite-like structure.

It is obtained chiefly from the mineral cassiterite, which contains tin dioxide. Neon is a chemical element with atomic number 10 which means there are 10 protons and 10 electrons in the atomic structure. On the other hand, water boils at 350°C (662°F) at 16.5 MPa (typical pressure of PWRs). Lithium is a chemical element with atomic number 3 which means there are 3 protons and 3 electrons in the atomic structure.
