"Curium Curium is a transuranic radioactive chemical element with symbol Cm and atomic number 96. This element of the actinide series was named after Marie and Pierre Curie – both were known for their research on radioactivity. Curium was first intentionally produced and identified in July 1944 by the group of Glenn T. Seaborg at the University of California, Berkeley. The discovery was kept secret and only released to the public in November 1947. Most curium is produced by bombarding uranium or plutonium with neutrons in nuclear reactors – one tonne of spent nuclear fuel contains about 20 grams of"

The Los Angeles–based enterprise started with development of the copper mines on the island of Cyprus. In antiquity, Cyprus was a major center for the production of copper, since the second or even third millenium BC. In fact, the Roman name for copper was ""aes cyprium"", from the name of Cyprus in Greek: Κύπρος, which is read as: Kypros. In later centuries ""aes cyprium"" became simply cyprium and then cuprum. This was further transformed and gave the word for copper"

Like in most other d-block groups, the abundance in Earth's crust of group 12 elements decreases with higher atomic number. Zinc is with 65 parts per million (ppm) the most abundant in the group while cadmium with 0.1 ppm and mercury with 0.08 ppm are orders of magnitude less abundant. Copernicium, as a synthetic element with a half-life of a few minutes, may only be present in the laboratories where it was"
"Mining industry of Cyprus The Mining industry of Cyprus is synonymous with copper extraction which began around 4,000 BC. Copper dominates the mining sector along with mining of iron pyrite, gold, chromites and asbestos fibers, bentonite, cement, and also petroleum. Though at one time, copper was a mainstay of the economy, as of 2012, the mining sector does not contribute in a significant way to the GNP. The name Cyprus is a derivative of Kúpros, which the Greeks called the island, and means Cuprous, synonymous with copper. Copper production can be dated to the fourth millennium BC, when it was"

"discovered, pharmacosiderite was known as cube ore. The present name, given by J. F. L. Hausmann in 1813, is made up of the Greek words for arsenic and iron, the two most significant consisting elements. ""Pharmakos"" means poison, which is related to arsenic, and ""sideros"" means iron. Pharmacolite and picropharmacolite, which are different arsenates, are not associated besides via nomenclature. Siderite, a carbonate mineral, only shares the common element iron with pharmacosiderite. Attribution: Pharmacosiderite Pharmacosiderite is a hydrated basic ferric arsenate, with chemical formula KFe(AsO)(OH)·(6-7)HO and a molecular weight of 873.38 g/mol.

During the standard six-month discussion period among the scientific community about the naming, it was pointed out that the symbol ""Cp"" was previously associated with the name ""cassiopeium"" (cassiopium), now known as lutetium (Lu). For this reason, the IUPAC disallowed the use of Cp as a future symbol, prompting the GSI team to put forward the symbol Cn as"

In the resting state, the Cu is also binding a water molecule that is displaced by nitrite. As nitrite displaces water, Cu is bound by both oxygens in a bidentate fashion. A nearby Aspartic acid residue hydrogen bonds to one of the newly formed oxygen ligands. An incoming electron reduces the Cu from oxidation state (II) to (I). This change facilitates a shift in nitrite binding so that the nitrogen is bound to Cu, and one"

In this structure there are 24 crystallographically distinct Cu atoms and the structure has been described as approximating to a hexagonal close packed array of sulfur atoms with Cu atoms in planar 3 coordination. This structure was initially assigned an orthorhombic cell due to the twinning of the sample crystal. There is also a crystallographically-distinct phase (the mineral djurleite)"
