who discovered a element Germanium?

New Niche Finder answers:

The Russian chemist Dmitry Mendeleyev predicted the existence and chemical properties of germanium in 1871; because of its position under silicon in the periodic table, he called it ekasilicon. The element was actually discovered in the silver-sulfide ore argyrodite by the German chemist Clemens Alexander Winkler in 1886.

Germanium, symbol Ge, hard, brittle, grayish-white, crystalline semimetallic element. The atomic number of germanium is 32; it is in group 14 (or IVa) of the periodic table (see Periodic Law).

Germanium is in the same chemical family as carbon, silicon, tin, and lead, and resembles these elements in forming organic derivatives such as tetraethyl germanium and tetraphenyl germanium. Germanium forms hydrides—germanomethane, or germane (GeH 4); germanoethane (Ge2H6); and germanopropane (Ge 3H8)—analogous to those formed by carbon in the methane series (see Chemistry, Organic). The most important compounds of germanium are the oxide GeO2 (germanic acid) and the halides. Germanium is separated from other metals by distillation of the tetrachloride.

Germanium ranks 54th in order of abundance of the elements in the earth’s crust. Germanium melts at about 937° C (about 1719° F), boils at about 2830° C (about 5126° F), and has a specific gravity of 5.3; its atomic weight is 72.59.

Germanium occurs in small quantities in the ores of silver, copper, and zinc, and in the mineral germanite, which contains 8 percent germanium. Germanium and its compounds are used in a variety of ways. Suitably prepared germanium crystals have the property of rectifying, or passing electrical currents in one direction only, and so were used extensively during and after World War II (1939-1945) as detectors for ultra-high-frequency radio and radar signals. Germanium crystals also have other specialized electronic uses. Germanium was the first metal used in the transistor, the electronic device that requires far less current than the vacuum tube. Germanium oxide is used in the manufacture of optical glass and as a drug in the treatment of pernicious anemia.

Maria asks…

who discovered oxygen element?

New Niche Finder answers:

Oxygen had been produced by several chemists prior to its discovery in 1774, but they failed to recognize it as a distinct element. Joseph Priestley and Carl Wilhelm Scheele both independently discovered oxygen, but Priestly is usually given credit for the discovery. They were both able to produce oxygen by heating mercuric oxide (HgO). Priestley called the gas produced in his experiments ‘dephlogisticated air’ and Scheele called his ‘fire air’. The name oxygen was created by Antoine Lavoisier who incorrectly believed that oxygen was necessary to form all acids.

Linda asks…

Who are six of the most famous people that discovered elements?

New Niche Finder answers:

It is a great achievement to discover a single element out of the 111 or so that are now known. So you may be surprised to find that there are several people who have discovered more than one element, in one case as many as 11. Here are some brief descriptions of the work of some chemists who discovered more than one element. In many cases they took advantage of a new technique.
·Jons Jacob Berzelius – reaction with carbon
·Humphry Davy – electrolysis
·Robert Bunsen – flame colours
·William Ramsay – the distillation of liquid air
·Marie Curie – radioactive elements
·Glenn T Seaborg – making new elements with sub-atomic particles

David asks…

Do you think anymore elements will be discovered?

New Niche Finder answers:

We discover new elements occasionally by fusion, their just so massive and unstable that they fall apart in fractions of a second, the question is will we discover high mass stable elements
