Your Questions About How To Discover New Elements

Laura asks…

What elements did Marie Curie discover?

Is it Polonium, Curium and Radium??

New Niche Finder answers:

Only Po and Ra
Cm is maked in 1944 form a three scientists team
I report form wiki :
Curium was first synthesized at the University of California, Berkeley by Glenn T. Seaborg, Ralph A. James, and Albert Ghiorso in 1944
It was chemically identified at the Metallurgical Laboratory (now Argonne National Laboratory) at the University of Chicago. It was actually the third transuranium element to be discovered even though it is the fourth in the series. Curium-242 (half-life 163 days) and one free neutron were made by bombarding alpha particles onto a plutonium-239 target in the 60-inch cyclotron at Berkeley.
94Pu239 + 2He4 —> 96Cm242 + on1
Plutonium-239 + Helium-4 make Curium-242 and one neutron
http://en.wikipedia.org/wiki/Curium
other informations about Curium :
ue to the fact that the discovery of the new elements, curium and americium, was closely related to the Manhattan Project the results were confidential and publication was impossible. Seaborg announced the discovery of the elements on the radio show for kids, the Quiz Kids, five days before the official presentation at an American Chemical Society meeting on November 11, 1945.[4] Seaborg also patented the synthesis of the new elements.[5]
Louis Werner and Isadore Perlman created a visible sample of curium-242 hydroxide at the University of California in 1947 by bombarding americium-241 with neutrons.[6] Curium was made in its elemental form in 1951 for the first time.[7][8]
good bye

Lisa asks…

what was the first element discovered?

New Niche Finder answers:

That is impossible to say. Many elements have been known since “antiquity”. There is no way to know which element was “discovered” first. Even at that, we have to wonder what it means to be “discovered”. Only when chemistry came into its own as a science in the 17th and 18th centuries, did early chemists understand the meaning of “element”.

Helen asks…

Who discovered the element Carbon?

And when?

New Niche Finder answers:

History and etymology

For recent discoveries see also: Timeline of carbon nanotubes

Carbon was discovered in prehistory and was known to the earliest human civilizations, who manufactured it by burning wood in insufficient oxygen, making charcoal.[citation needed]

In 1722, René A. F. De Réaumur demonstrated that iron was transformed into steel through the absorption of some substance, now known to be carbon[4]. In 1772, Antoine Lavoisier showed that diamonds are a form of carbon, when he burned samples of carbon and diamond then showed that neither produced any water and that both released the same amount of carbon dioxide per gram. Carl Wilhelm Scheele showed that graphite, which had been thought of as a form of lead, was instead a type of carbon.[5] In 1786, the French scientists Claude Louis Berthollet, Gaspard Monge and C. A. Vandermonde then showed that this substance was carbon.[6] In their publication they proposed the name carbone (Latin carbonum) for this element. Antoine Lavoisier listed carbon as an element in his 1789 textbook.[7]

The name of carbon comes from Latin carbo, hence comes French charbon, meaning charcoal. In German, Dutch and Danish, the names for carbon are Kohlenstoff, koolstof and kulstof respectively, all literally meaning coal-substance.

New, exotic allotropes of carbon have been discovered recently, including glassy carbon, and nanostructured forms called fullerenes, which occur in the form of buckyballs such as C60, nanotubes[8][9], and nanofibers[10

William asks…

what branch of chenistry would you use to discover element 110?

New Niche Finder answers:

Nuclear chemistry…

Darmstadtium, formerly called ununnilium (IPA:, symbol Uun) or eka-platinum, is a chemical element with the symbol Ds and atomic number 110. It is one of the so-called super-heavy atoms. This synthetic element quickly decays: its isotopes of mass 267 to 273 have half-lives measured in microseconds. Heavier isotopes, of mass 279 and 281, have been subsequently synthesized and are more stable, with half-lives of 180 milliseconds and 11.1 seconds, respectively.
Ds was first generated on November 9, 1994 at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany. Only a few atoms of it were prepared by the nuclear fusion by bombarding a lead target with nickel.

Nuclear chemistry is a subfield of chemistry dealing with radioactivity, nuclear processes and nuclear properties. It may be divided into four categories including:
The application of techniques from chemistry to study nuclear reactions such as fission and fusion.

DoubtingT’s answer refers to a reference to a paper in a professional journal published by IUPAC the International Union of Pure and Applied Chemistry, this not a branch of Chemistry per se but covering all of Chemistry.

James asks…

When and how did Alfred Nobel discover the element nobelium?

New Niche Finder answers:

LOL. Rolling on the floor, LOL.

The element nobelium was named in HONOR of Nobel. He was long dead when nobelium was made/discovered.

“It was first correctly identified in 1956 by scientists at the Flerov Laboratory of Nuclear Reactions in Dubna, Russia.”
http://en.wikipedia.org/wiki/Nobelium

There was much wrangling about the discovery after that. Read the Wikipedia article.

“Element 102 was first named nobelium (No) by its claimed discoverers in 1957 by scientists at the Nobel Institute in Sweden. The name was later adopted by Berkeley scientists who claimed its discovery in 1959.”

Finally, scientists have never named elements after themselves.
