In Stockholm, Arfwedson knew the chemist Jöns Jakob Berzelius and received access to his private laboratory, where he discovered the element lithium in 1817, during analysis of the mineral petalite. [1] The actual isolation of lithium metal would be done by others. In 1818 and 1819, Arfwedson made a European journey, partly in the society of ...
He named the new element "lithium". [10] [74] [79] Arfwedson later showed that this same element was present in the minerals spodumene and lepidolite. [81] [74] In 1818, Christian Gmelin was the first to observe that lithium salts give a bright red color to flame.
[174] [175] Hafnium was the last stable element to be discovered (noting however the difficulties regarding the discovery of rhenium). 43 Technetium: 1937 C. Perrier and E. Segrè: 1947 S. Fried [176] The two discovered a new element in a molybdenum sample that was used in a cyclotron, the first element to be discovered by synthesis. It had ...

Rubidium and caesium were the first elements to be discovered using the spectroscope, invented in 1859 by Robert Bunsen and Gustav Kirchhoff. [22] The next year, they discovered caesium in the mineral water from Bad Dürkheim, Germany. Their discovery of rubidium came the following year in Heidelberg, Germany, finding it in the mineral ...
Three important developments regarding lithium batteries occurred in the 1980s. In 1980, an American chemist, John B. Goodenough, discovered the LiCoO 2 (Lithium cobalt oxide) cathode (positive lead) and a Moroccan research scientist, Rachid Yazami, discovered the graphite anode (negative lead) with the
Global production of lithium – an essential mineral for manufacturing the lithium-ion batteries that are found in everything from smartphones to electric cars – has tripled over the last 10 ...
The heaviest discovery to date, element 118 oganesson, was made using a beam of calcium isotope 48 particles. Calcium 48, with its definitive 20 protons plus 28 neutrons, is a common and very ...
