There is a precedent for a name change, since an even earlier name for the elements was "lanthanon." The lanthanides or F Block elements are a set of elements of the periodic table. Furthermore, the name is not pr… elements list - Lanthanides - Also called Rare Earth Metals, these elements are very uncommon on Earth. All of the others have only been artificially made in the laboratory. Group number of Metals However, the International Union of Pure and Applied Chemistry, the international body in charge of chemical nomenclature, prefers the term lanthanoid, since the -ide ending is usually reserved for negatively charged ions. The term "rare earths" arises from the minerals from which they were isolated, which were uncommon oxide-type minerals. Bright and silvery in appearance, many of the lanthanidesthough they are metalsare so soft they can be cut with a knife. One of those rows is called the lanthanide series. De lanthaniden, door IUPAC recent bij voorkeur lanthanoïden genoemd, vormen een serie van 15 elementen van atoomnummer 57 tot en met 71. The lanthanide contraction is the greater-than-expected decrease in ionic radii of the elements in the lanthanide series from atomic number 57, lanthanum, to 71, lutetium, which results in smaller than otherwise expected ionic radii for the subsequent elements starting with 72, hafnium. The lanthanide elements are all typically trivalent and are almost identical in size, and their chemical properties are almost identical. The use of this name is deprecated by IUPAC, as they are neither rare in abundance nor "earths" (an obsolete term for water-insoluble strongly basic oxides of electropositive metals incapable of being smelted into metal using late 18th century technology). lanthanide elements list. odd elements is smaller than the abundance of neighboring Z-even elements. Meet the Family These metals are also widely used in the petroleum industry for refining of crude oil into gasoline products. are also furnished for knowledge seekers.
