Your Questions About How To Discover New Elements

James asks…

who discovered the elements?

New Niche Finder answers:

Alot of them were discovered be Mendeleev
http://en.wikipedia.org/wiki/Dmitri_Mendeleev

However other people discovered and even created some of the other known elements. And about 94 of them are naturally occurring the rest are created in labs.

Susan asks…

Who discovered the elements boron and einsteinium?

New Niche Finder answers:

Niels Bohr and Albert Einstein.

Ba-dum tish!

No.

Boron was discovered by Joseph-Louis Gay-Lussac and Louis-Jaques Thénard and independently by Sir Humphry Davy, both in 1808, by the reduction of borax (Na2B4O7·10H2O) by potassium to elemental boron. It wasn’t formally recognized as an element until the 1820s — keep in mind that this was long enough ago that Dalton’s atomic theory was still a crazy new-fangled idea that hadn’t quite caught on yet.

Einsteinium is not naturally occurring. It was discovered by Albert Ghiorso and a team of other Berkeley Radiation Lab (now the Lawrence Berkeley National Lab) scientists studying the radioactive detrius from the first hydrogen bomb detonation in 1952. They found 253Es, which is stable enough to hang around for a while (half-life about 21 days), but not actually the longest lived isotope: 252Es and 254Es were synthesized later at the Berkeley Lab, and have half-lives of over a year.

Say what? Boron is pronounced as BO-ron.

History and Uses:

Boron was discovered by Joseph-Louis Gay-Lussac and Louis-Jaques Thénard, French chemists, and independently by Sir Humphry Davy, an English chemist, in 1808. They all isolated boron by combining boric acid (H3BO3) with potassium. Today, boron is obtained by heating borax (Na2B4O7·10H2O) with carbon, although other methods are used if high-purity boron is required.

Boron is used in pyrotechnics and flares to produce a green color. Boron has also been used in some rockets as an ignition source. Boron-10, one of the naturally occurring isotopes of boron, is a good absorber of neutrons and is used in the control rods of nuclear reactors, as a radiation shield and as a neutron detector. Boron filaments are used in the aerospace industry because of their high-strength and lightweight.

Boron forms several commercially important compounds. The most important boron compound is sodium borate pentahydrate (Na2B4O7·5H2O). Large amounts of this compound are used in the manufacture of fiberglass insulation and sodium perborate bleach. The second most important compound is boric acid (H3BO3), which is used to manufacture textile fiberglass and is used in cellulose insulation as a flame retardant. Sodium borate decahydrate (Na2B4O7·10H2O), better known as borax, is the third most important boron compound. Borax is used in laundry products and as a mild antiseptic. Borax is also a key ingredient in a substance known as Oobleck, a strange material 6th grade students experiment with while participating in Jefferson Lab’s BEAMS program. Other boron compounds are used to make borosilicate glasses, enamels for covering steel and as a potential medicine for treating arthritis.

Mary asks…

Who discover the element Platinum?

what year? and how many protonsneutrons and electrons does it have >

New Niche Finder answers:

Platinum was discovered by astronomers Antonio de Ulloa and Don Jorge Juan y Santacilia in 1735. However the first European reference to platinum appears in 1557 in the writings of the Italian humanist Julius Caesar Scaliger (1484-1558). Charles Wood independently isolated the element in 1741. The alchemical symbol for platinum was made by joining the symbols of silver and gold.

Hope this helps!

Helen asks…

who discovered the element neon?

New Niche Finder answers:

Neon was discovered by Sir William Ramsay, a Scottish chemist, and Morris M. Travers, an English chemist, shortly after their discovery of the element krypton in 1898. Like krypton, neon was discovered through the study of liquefied air. Although neon is the fourth most abundant element in the universe, only 0.0018% of the earth’s atmosphere is neon.
