The classification of minerals is a process of determining to which of several groups minerals belong based on their chemical characteristics. Since the 1950s, this classification has been carried out by the International Mineralogical Association , which classifies minerals into the following broad classes:
Calcium-60 is the heaviest known isotope as of 2020. [1] First observed in 2018 at Riken alongside 59 Ca and seven isotopes of other elements, [ 26 ] its existence suggests that there are additional even- N isotopes of calcium up to at least 70 Ca, while 59 Ca is probably the last bound isotope with odd N .

Class A metals are metals that form hard acids. [1] Hard acids are acids with relatively ionic bonds. These metals, such as iron, aluminium, titanium, sodium, calcium, and the lanthanides, would rather bond with fluorine than iodine. They form stable products with hard bases, which are bases with ionic bonds. They target molecules such as ...
Benzothiazepine calcium channel blockers belong to the benzothiazepine class of compounds and are an intermediate class between phenylalkylamine and dihydropyridines in their selectivity for vascular calcium channels. By having both cardiac depressant and vasodilator actions, benzothiazepines are able to reduce arterial pressure without ...
Kidney stones: Cranberries contain oxalates, so they may increase your risk for kidney stones (which are made of calcium oxalate) when consumed in large quantities, says Karp. It’s best to limit ...
