Here's a quick list: Actinide Metals, Lanthanide Metals, Alkali Metals, Alkaline-Earth Metals, Rare Metals, Rare-Earth Metals, and Transition Metals. Remember, that's the easy list. Lucky for you, the periodic table is excellent at organizing elements, and you will find each of these groups in specific areas of the periodic table.
KREEP, an acronym built from the letters K (the atomic symbol for potassium), REE (rare-earth elements) and P (for phosphorus), is a geochemical component of some lunar impact breccia and basaltic rocks. Its most significant feature is somewhat enhanced concentration of a majority of so-called "incompatible" elements (those that are concentrated in the liquid phase during magma crystallization ...
The simple definition is that KREEP is an acronym for potassium (chemical symbol K), rare earth elements (the ones that are always cut out of the periodic table and drawn in two separate rows of their own, abbreviated REE), and phosphorus (chemical symbol P).
The Metals. The alkali metals, lithium (Li), sodium (Na), potassium (K), rubidium (Rb) and cesium (Cs), are all extremely light in weight, compressible, and relatively, very soft.Lithium is the hardest of the alkali metals with a hardness of 0.6 on Mohs' scale. Freshly cut surfaces of the alkali metals show a silvery white luster, which tarnishes quickly and becomes dull in air.
The present invention relates to a lead-free piezoelectric potassium sodium niobate-based photo - electric multifunctional material and its preparation method belongs to the field emissive material. Using a synergistic combination effect between the rare earth ions and metal ions, and significantly improved fluorescence properties of the piezoelectric potassium sodium niobate-based lead-free ...

Solubility of Rare Earth Hydroxides in Aqueous Sodium Potassium Tartrate 317 undissolved after treatment with Rochelle salt solution. The quantity measured was the weight of oxide in the filtrate. This was done by igniting the precipitated oxalate and also by titrating its sulphuric acid solution
identity. Coordination numbers of eight are, therefore, possible for the rare-earth ions. The most striking feature of these results are the remarkably low bl/bz values for the Ad-d-d and M-d-1 complexes. The b2 values listed in Table I11 show that it is more
A series of potassium lead borophosphate glass doped with rare earth and transition metal ions were fabricated using melt-quenching method without annealing process. With the composition of glass 0.15K2O – 0.15PbO – 0.35B2O3 – 0.5P2O5 as host doped

Rare earth elements+Potassium fertilizer Description:This product was developed by my company to meet the crops fertilizer demand at different growth stage, it containing rare earth elements and a large amount of potassium.
A facile one-pot flux method was applied to fabricate K 2 RETa 5 O 15 (RE = rare-earth element) with tetragonal tungsten bronze (TTB) structures. Pure TTB structures of K 2 RETa 5 O 15 (RE = La, Ce, Pr, Nd, and Sm) with rod-like morphologies were obtained using KCl as the potassium source and flux. For other potassium rare-earth tantalates, the TTB structure was dominant, with an additional ...

Mar 05, 2019· Rare Earths and Rare Earth. In 2000, Ward and Brownlee published a controversial book, Rare Earth: Why Complex Life Is Uncommon in the Universe. At a time when most scientists assumed there must be millions of complex civilizations in the Milky Way alone, the authors rained on their parade, arguing that the requirements for complex life are so ...
Is potassium a family name or a rare earth element series? potassium is an element on the periodic table. it is an alkali metal. How did potassium get its name?
Most elements are metals. This group includes the alkali metals, alkaline earth metals, transition metals, basic metals, lanthanides (rare earth elements), and actinides. Although separate on the periodic table, the lanthanides and actinides are really specific types of transition metals.

Interesting Facts about Potassium. Its earliest use was in making soaps. It reacts violently with water, causing eruptions. The potassium salts are mined in Germany and the USA. It is never found free in nature, but has to be obtained by electrolysis. It makes up about 2.4% of the weight of the Earth's crust.
