Who Discovered Bromine Bromine was first discovered by Carl Jacob in 1825. He isolated bromine from a mineral spring water in his hometown Bad Krueznach. He saturated a solution of the mineral with chlorine and extracted bromine by using an ether. A brown liquid (bromine) remained!

Polonium: the essentials Polonium was the first element discovered by Marie Sklodowska Curie in 1898, while seeking the cause of radioactivity of pitchblende from Joachimsthal, Bohemia.It required several tonnes of pitchblende to produce very small amounts of polonium.olonium is produced through decay of the small quantities of the bismuth isotope 210 Bi present in pitchblende (uranite, largely UO 2). However the quantities are very small. Uranium ores might contain about 0.0001 g of polonium in a tonne of ore.

Bromine Natural bromine is a mixture of two stable isotopes: bromine-79 (50.54 percent) and bromine-81 (49.46 percent). Of the 17 known radioactive isotopes of the element, bromine-77 has the longest half-life (57 hours).

- Gold was first discovered as shining, yellow nuggets. Gold is where you find it, so the saying goes, and gold was first discovered in its natural state, in streams all over the world. No doubt it was the first metal known to early hominids.

- The element bromine exists as a diatomic molecule, Br 2. It is a dense, mobile, slightly transparent reddish-brown liquid, that evaporates easily at standard temperature and pressures to give an orange vapor (its color resembles nitrogen dioxide) that has a strongly disagreeable odor resembling that of chlorine.romine is rarer than about three-quarters of elements in the Earth 's crust. The high solubility of bromide ions has caused its accumulation in the oceans, and commercially the element is easily extracted from brine pools, mostly in the United States, Israel and China.

What New-Car Fees Should You Pay? If there is a Y in the Trade-In Sales Tax column of your state, you are only taxed on the difference between the new car and your trade-in. So, if your new car costs $25,000 and you are getting $10,000 for your trade-in, you will only be taxed on the difference, or $15,000.If sales tax in your state is 10 percent, this will save you $1,000.If there is an N in the column, it means that you will pay tax on the full amount of your new car purchase, and the trade-in has no bearing on the sales tax you are charged.sually, the more expensive the car is, the higher the registry fees. Sales Tax: Sales tax on a new car amounts to more than most people expect. For example, at 8 percent, sales tax on a $20,000 car will cost you $1,600.

Uranium The 1789 discovery of uranium in the mineral pitchblende is credited to Martin Heinrich Klaproth, who named the new element after the planet Uranus. Eugène-Melchior Péligot was the first person to isolate the metal and its radioactive properties were discovered in 1896 by Henri Becquerel.

Yttrium General | States | Energies | Oxidation & Electrons | Appearance & Characteristics | Reactions | Compounds | Radius | Conductivity | Abundance & Isotopes. Yttrium was discovered by Johan Gadolin in 1794 in the mineral gadolinite. Yttrium metal was first isolated in 1828 when Friedrich Wöhler heated anhydrous yttrium (III) chloride with potassium. The element was named after the Swedish village of Ytterby, where it was mined.

Radium: the essentials Radium was discovered by Pierre and Marie Curie in 1898 at France. Origin of name: from the Latin word  radius  meaning  ray . Radium was discovered in 1898 by Marie and Pierre Curie in pitchblende (or uraninite) from North Bohemia. The element was isolated in 1911 by Mme.Curie and Debierne by the electrolysis of a solution of pure radium chloride, employing a mercury cathode.adium was discovered by Pierre and Marie Curie in 1898 at France.

- The element bromine exists as a diatomic molecule, Br 2. It is a dense, mobile, slightly transparent reddish-brown liquid, that evaporates easily at standard temperature and pressures to give an orange vapor (its color resembles nitrogen dioxide) that has a strongly disagreeable odor resembling that of chlorine.he diatomic element Br 2 does not occur naturally. Instead, bromine exists exclusively as bromide salts in diffuse amounts in crustal rock. Owing to leaching, bromide salts have accumulated in sea water at 65 parts per million (ppm), which is less than chloride.

Bromine The simplest compound of bromine is hydrogen bromide, HBr. It is mainly used in the production of inorganic bromides and alkyl bromides, and as a catalyst for many reactions in organic chemistry. Industrially, it is mainly produced by the reaction of hydrogen gas with bromine gas at 200–400 °C with a platinum catalyst.

- Dr. Marie Curie is known to the world as the scientist who discovered radioactive metals such as radium and polonium. Curie was a Polish physicist and chemist who lived between 1867-1934. She was born Maria Sklodowski in Warsaw, Poland, the youngest of five children. When she was born, Poland was controlled by Russia.

POLONIUM (REVISED) Polonium was discovered in 1898 by Polish-French physicist Marie Curie (1867-1934) and her husband, Pierre (1859-1906). They were looking for the source of radioactivity in a naturally occurring ore called pitchblende. Radioactivity is the process by which materials give off energy and change into new materials. Polonium is the heaviest element in the chalcogen family. It is in Group 16 (VIA) on the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. The other chalcogen elements are oxygen, sulfur, selenium, and tellurium.
