Br 2 + H 2 O → HBr + HBrO. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. These condensers use tubes that are usually made of stainless steel, copper alloys, or titanium depending on several selection criteria (such as thermal conductivity or corrosion resistance). It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. 1) You may use almost everything for non-commercial and educational use. Mendelevium is a metallic radioactive transuranic element in the actinide series, it is the first element that currently cannot be produced in macroscopic quantities. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels. It is a dense and reddish-brown compound that evaporates quickly at room temperature to a red vapor with a strong, chlorine-like odor. Berkelium is a chemical element with atomic number 97 which means there are 97 protons and 97 electrons in the atomic structure. Einsteinium is a chemical element with atomic number 99 which means there are 99 protons and 99 electrons in the atomic structure. Elemental sulfur is a bright yellow crystalline solid at room temperature. The chemical symbol for Aluminum is Al. Americium is a transuranic member of the actinide series, in the periodic table located under the lanthanide element europium, and thus by analogy was named after the Americas. 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”. Uranium has the highest atomic weight of the primordially occurring elements. Uranium is a silvery-white metal in the actinide series of the periodic table. Ltd., Bharuch, Gujarat. Bromine was discovered by a French chemist - Antoine J.Balard, in 1826. 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’. The chemical symbol for Plutonium is Pu. If you continue to use this site we will assume that you are happy with it. 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. Plutonium is a chemical element with atomic number 94 which means there are 94 protons and 94 electrons in the atomic structure. Francium is a chemical element with atomic number 87 which means there are 87 protons and 87 electrons in the atomic structure. Titanium is resistant to corrosion in sea water, aqua regia, and chlorine. Francium is an alkali metal, that has one valence electron. Other names – Dibromine, Bromine solution, Your email address will not be published. It gives dense red-brown vapours, and these are highly toxic to mucous membranes. Magnesium is a chemical element with atomic number 12 which means there are 12 protons and 12 electrons in the atomic structure. Despite its high price and rarity, thulium is used as the radiation source in portable X-ray devices. Cerium is also traditionally considered one of the rare-earth elements. Carbon is one of the few elements known since antiquity. properties are intermediate between those of iodine and chlorine. is a molecule formed when two bromine atoms combine together. The chemical symbol for Antimony is Sb. Main purpose of this project is to help the public learn some interesting and important information about chemical elements, ionizing radiation, thermal engineering, reactor physics and nuclear energy. As a solid is heated, its particles vibrate more rapidly as the solid absorbs kinetic energy. Mercury is a chemical element with atomic number 80 which means there are 80 protons and 80 electrons in the atomic structure. Only about 5×10−8% of all matter in the universe is europium. They are also poisonous to humans in many cases. Bromine is less chemically active than that of chlorine and fluorine but more active than iodine; its compounds are much similar to those of other halogens. Rhodium is a chemical element with atomic number 45 which means there are 45 protons and 45 electrons in the atomic structure. A major development was the discovery that steel could be made highly resistant to corrosion and discoloration by adding metallic chromium to form stainless steel. Argon is the third-most abundant gas in the Earth’s atmosphere, at 0.934% (9340 ppmv). Bromine evaporates quickly at room temperature due to its liquid state. Bromine is the third-largest halogen, and the Br. Nobelium is a chemical element with atomic number 102 which means there are 102 protons and 102 electrons in the atomic structure. Bromine is purified from the salts taken from rocks and seawater. Francium is a highly radioactive metal that decays into astatine, radium, and radon. Titanium condenser tubes are usually the best technical choice, however titanium is very expensive material. Because of its closed-shell electron configuration, its density and melting and boiling points differ significantly from those of most other lanthanides. Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure. Argon is mostly used as an inert shielding gas in welding and other high-temperature industrial processes where ordinarily unreactive substances become reactive; for example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. When considered as the temperature of the reverse change from liquid to solid, it is referred to as the freezing point or crystallization point. Discoverer: Corson, Dale R. and Mackenzie, K. R. The actinide or actinoid series encompasses the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium. 2. Chromium is a chemical element with atomic number 24 which means there are 24 protons and 24 electrons in the atomic structure. Discoverer: Scientists at Dubna, Russia (1964)/Albert Ghiorso et. Bromine is a chemical element with atomic number 35 which means there are 35 protons and 35 electrons in the atomic structure. Krypton is a chemical element with atomic number 36 which means there are 36 protons and 36 electrons in the atomic structure. Pro Lite, CBSE Previous Year Question Paper for Class 10, CBSE Previous Year Question Paper for Class 12. Major advantage of lead shield is in its compactness due to its higher density. Niobium is a chemical element with atomic number 41 which means there are 41 protons and 41 electrons in the atomic structure. The chemical symbol for Boron is B.
