Most elements on the periodic table are metals. They are grouped together in the middle to the left-hand side of the periodic table. The metals consist of the alkali metals, alkaline earths, transition metals, lanthanides, and actinides.. Here is a list of metals, their location on the periodic table, their properties, and uses.
The principal economic sources of rare earths are the minerals bastnasite, monazite, and loparite and the lateritic ion-adsorption clays. The rare earths are a relatively abundant group of 17 elements composed of scandium, yttrium, and the lanthanides. The elements range in crustal abundance from cerium, the 25th most abundant element of the 78 common elements in the Earth's
A scarcity in rare diamonds sends global prices skyrocketing. November 2020 marked a critical moment in time for diamond connoisseurs worldwide as Rio Tinto's Argyle Mine in East Kimberley, Western Australia ceased operation after 37 years of production, translating to a loss of 90 per cent in the world's annual supply of precious pink ...
Most rare earth elements are actually relatively abundant in the earth's crust, but are rarely concentrated in economically useful forms With the exception of unstable promethium (estimated 572 grams total in the entire crust!), all the REEs are more abundant than silver or mercury. However, rare earths are not often concentrated in mineable deposits, and are almost always found in conjunction ...

Metal audits. A Metal Audit is an 60-120 hardcover report of a metal whose market, manufacturer, seller, buyer, product and ownership represents. Audits are usually for auditors and banks, which must quantify the value of a stock in stock and also need a basis and justification. An audit assesses an entire lot of a particular product.
Astatine is a chemical element with the symbol At and atomic number 85. It is the rarest naturally occurring element in the Earth's crust, occurring only as the decay product of various heavier elements. All of astatine's isotopes are short-lived; the most stable is astatine-210, with a half-life of 8.1 hours. A sample of the pure element has never been assembled, because any macroscopic ...
Angular rough shark, Oxynotus centrina (Linnaeus, 1758), is a poorly known and rare bathydemersal shark inhabiting continental shelves and upper slopes with a significant lack of data and almost no published records in the Adriatic Sea in this century. In this paper, we present 20 new occurrences recorded from May 2015 to September 2021, of ...
rare earth, is more abundant than cobalt. Yttrium is more abundant than lead, whereas Lu and Tm are as abundant as Sb, Hg, Bi, and Ag. For all practical purposes promethium does not occur in nature. It forms only in nuclear reactors. Raw material The major raw material for rare earths is monazite sand, xenotime, bastnasite, and phosphate rock.

Promethium is a chemical element with the symbol Pm and atomic number 61. All of its isotopes are radioactive; it is extremely rare, with only about 500–600 grams naturally occurring in Earth's crust at any given time.Promethium is one of only two radioactive elements that are followed in the periodic table by elements with stable forms, the other being technetium.
Promethium sits in the lanthanides, the floating bar of elements that squeezes between barium and lutetium. The rare earth elements either side of it, neodymium and samarium, seemed not to have the right relationship in their chemical properties to be neighbours. It was as if there were a gap between, and Czech chemist John Bohuslav Branner ...
"Promethium," Bruce answered absently. "It's one of the rare-earth elements, the one we were going to use to replicate the radioactive properties of the Tesseract. It's mostly used for atomic batteries." "I don't think there's this much promethium on Earth," Tony said. "I don't think this much promethium …

Rare earth elements are a group of seventeen chemical elements that occur together in the periodic table (see image). The group consists of yttrium and the 15 lanthanide elements (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium).

Promethium is an extremely rare element and only 500-600g of promethium is naturally present in the earth's crust. Promethium is not found in free or elemental form in nature. It is found in uranium ores. It can be produced as a by -product of uranium fission reaction. Uranium is responsible for 560g of promethium in the Earth crust.
