Garnet - Wikipedia

Etymology. The word garnet comes from the 14th‑century Middle English word gernet, meaning ''dark red''.It is borrowed from Old French grenate from Latin granatus, from granum (''grain, seed''). This is possibly a reference to mela granatum or even pomum granatum (''pomegranate'', Punica granatum), a plant whose fruits contain abundant and vivid red seed covers (), which are …

calcium channel blocker (calcium channel blocking agent) a drug such as nifedipine, diltiazem, or verapamil that selectively blocks the influx of calcium ions through a calcium channel of cardiac muscle and smooth muscle cells; used in the treatment of Prinzmetal''s angina, chronic stable angina, and cardiac arrhythmias.Calcium channel blocking agents act to control …

Hardness - Water Quality Association

Hard water is a common quality of water which contains dissolved compounds of calcium and magnesium and, sometimes, other divalent and trivalent metallic elements. Dissolved calcium and magnesium salts are primarily responsible for most scaling in pipes and water heaters and cause numerous problems in laundry, kitchen, and bath.

Ionic radius - Wikipedia

Ionic radius, r ion, is the radius of a monatomic ion in an ionic crystal structure. Although neither atoms nor ions have sharp boundaries, they are sometimes treated as if they were hard spheres with radii such that the sum of ionic radii of the ion and anion gives the distance between the ions in a crystal lattice.Ionic radii are typically given in units of either picometers (pm) or

Divalent ion - an overview | …

Divalent ions (those divalent ions that may affect sulfhydryl residues, such as Cu 2+ or Hg 2+, are not included in this discussion) may be classified into three egories: (1) magnesium and manganese ions, which can induce contractile responses, i.e., can give rise to the actin-activated ATPase, superprecipitation, and clearing response; (2) calcium and strontium ions, …

Soil Management - University of Hawaiʻi

By definition, it is the percentage of calcium, magnesium, potassium and sodium ions that make up the total ion exchange capacity. Additionally, in such a soil, potassium (a monovalent ion) will leach more readily than calcium (divalent ion) since calcium is more strongly held to the soil particles than potassium.
