Palladium, platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs). It is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.

Uranium is a silvery-white metal in the actinide series of the periodic table. The first alloy used on a large scale was bronze, made of tin and copper, from as early as 3000 BC.

The RSC maintains this Site for your information, education, communication, and personal entertainment. It is the heaviest essential mineral nutrient. All Rights Reserved. Rhenium was the lower one and indeed it was the last stable, non-radioactive, naturally-occurring element to be discovered. Bismuth is a brittle metal with a silvery white color when freshly produced, but surface oxidation can give it a pink tinge. Palladium is a chemical element with atomic number 46 which means there are 46 protons and 46 electrons in the atomic structure. Holmium is a relatively soft and malleable silvery-white metal. It does not occur uncombined in nature or as a compound in a mineable mineral species. The chemical symbol for Copper is Cu. The chemical symbol for Mercury is Hg. The name xenon for this gas comes from the Greek word ξÎνον [xenon], neuter singular form of ξÎÎ½Î¿Ï [xenos], meaning âforeign(er)â, âstrange(r)â, or âguestâ. Thorium is a naturally-occurring element and it is estimated to be about three times more abundant than uranium.
Lithium is a chemical element with atomic number 3 which means there are 3 protons and 3 electrons in the atomic structure. The chemical symbol for Argon is Ar. These have similar chemical properties, but palladium has the lowest melting point and is the least dense of them. Unraveling the mysteries of rhenium, here's UCLA's Eric Scerri. His claim too was largely discredited but as recently as 2004 it has emerged that he had in fact isolated rhenium well before the Noddacks. in fluorescent lamps, where it is a yellow colour, and as with europium(III) which is red, provides one of the primary colours in TV screens; who knew that Turbium could be in your TV set! Rhenium is element 75 in the periodic table and in many ways a rather unusual element. As the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine. For example, it shows the largest range of oxidation states of absolutely any known element, namely -1, 0, +1, +2 and so on all the way to +7, the last of which is actually its most common oxidation state. Selenium is a nonmetal with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic. For atoms with many electrons, this notation can become lengthy and so an abbreviated notation is used. The chemical symbol for Europium is Eu.
The metal is found in the Earthâs crust in the pure, free elemental form (ânative silverâ), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite.
The periodic table had two vacant slots below manganese and finding these missing elements, technetium and rhenium, proved difficult. Gold is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Iodine is the least abundant of the stable halogens, being the sixty-first most abundant element. In the periodic table, potassium is one of the alkali metals. Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry. The number of protons in an atom. The chemical symbol for Thorium is Th. Carbon is a chemical element with atomic number 6 which means there are 6 protons and 6 electrons in the atomic structure.
