Periodic table history He predicted the discovery of other elements, and left spaces open in his periodic table for them. In 1886 French physicist Antoine Bequerel first discovered radioactivity. Thomson student from New Zealand Ernest Rutherford named three types of radiation; alpha, beta and gamma rays.

- Protactinium (atomic number 91) is a metal discovered by Oswald Gohring and Kasimir Fajans in 1913. It was only in 1934 when the element was first isolated. Protactinium-231 was discovered by John Cranston and Frederick Soddy and Lisa Meitner and Otto Hahn in 1918.This metal is found in uranium ores while its isotopes are present in uranium-238 and uranium-235.Protactinium is a rare metal that reacts with inorganic acids, water vapor, and oxygen.It is toxic, radioactive, and harmful for human health. Because protactinium is a rare element, it is not used for commercial purposes and only for scientific research.pent nuclear fuel is also used to extract the metal. In households, it is found in smoke detectors in the form of protactinium-233 which is the product of decay of neptunium-237. The isotope itself has a half life of only 27 days (in comparison, the half life of protactinium-231 is over 32,000 years).

Humphry Davy Sir Humphry Davy, 1st Baronet PRS MRIA FGS was a Cornish chemist and inventor, who is best remembered today for isolating a series of substances for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as discovering the elemental nature of chlorine and iodine. He also studied the forces involved in these separations, inventing the new field of electrochemistry. In 1799 Davy experimented with nitrous oxide and became astonis

nuclide A nuclide (from nucleus) is an atomic species characterized by the specific constitution of its nucleus, i.e., by its number of protons Z, its number of neutrons N, and its nuclear energy state. The word nuclide was proposed by Truman P. Kohman in 1947.

It's Elemental Nobelium is pronounced as no-BELL-ee-em. History and Uses: In 1957, a group of scientists working at the Nobel Institute of Physics in Stockhlom, Sweden, announced the discovery of a new element.obelium's most stable isotope, nobelium-259, has a half-life of about 58 minutes. It decays into fermium -255 through alpha decay, into mendelevium -259 through electron capture or through spontaneous fission.

Polonium Element Facts Polonium, also called Radium F, was the first element discovered by Marie S. Curie. She discovered it in 1898 while investigating radioactivity in pitchblende (uranium oxide). The element is named after Poland, the country of Curie's birth.olonium is a rare, silvery-gray, radioactive low-melting metalloid. Polonium readily reacts with dilute acids, but only slightly with alkalis. All of its isotopes are radioactive. 210 Po emits a blue glow, as the air around it is excited by the decay products.

- A nuclide, also known as an isotope, …is a nucleus with a specified number of both protons and neutrons. So, for example, we know that the element carbon always has six protons in its nucleus; that is what makes it carbon rather than a different element. But it can have different numbers of neutrons.

Neptunium When Neptunium was first discovered in 1940, it was the first synthetic transubstantiation be discovered. Which means that it was the first man made element. This element was produced by two men, McMillan and Abelson. They were at the University of California in Berkley while this discovery took place.

Barium: historical information Barium: historical information. Barium was discovered by Sir Humphrey Davy at 1808 in England. Baryta (barium oxide, BaO) was distinguished from lime (calcium oxide, CaO) by Scheele in 1774. Elemental barium was isolated by Sir Humphrey Davy in 1808 who electrolysed molten baryta. Sometime prior to the autumn of 1803, the Englishman John Dalton was able to explain the results of some of his studies by assuming that matter is composed of atoms and that all samples of any given compound consist of the same combination of these atoms.
