Chemical element with the symbol Na and atomic number 11.
By means of the sodium-potassium pump, living human cells pump three sodium ions out of the cell in exchange for two potassium ions pumped in; comparing ion concentrations across the cell membrane, inside to outside, potassium measures about 40:1, and sodium, about 1:10.
Alkali metal
11 linksThe alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).
Mineral
10 linksIn geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.

These eight elements, summing to over 98% of the crust by weight, are, in order of decreasing abundance: oxygen, silicon, aluminium, iron, magnesium, calcium, sodium and potassium.
Potash
6 linksPotash is the name used for various mined and manufactured salts that contain potassium in water-soluble form.

Starting the next row, for potassium and calcium the 4s orbital is the lowest in energy, and therefore they fill it.
Chemical element
10 linksSpecies of atoms that have a given number of protons in their nuclei, including the pure substance consisting only of that species.

"W" (wolfram) for tungsten ultimately derives from German, "K" (kalium) for potassium ultimately from Arabic.
Lithium
6 linksChemical element with the symbol Li and atomic number 3.
Chemical element with the symbol Li and atomic number 3.
Like the other alkali metals (which are sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr)), lithium has a single valence electron that is easily given up to form a cation.
Potassium chloride
7 linksPotassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine.
Soap
6 linksSalt of a fatty acid used in a variety of cleansing and lubricating products.

When M is Na (Sodium) or K (Potassium), the soaps are called toilet soaps, used for handwashing.
Granite
6 linksCoarse-grained intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase.
Coarse-grained intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase.
Two-mica granites are typically high in potassium and low in plagioclase, and are usually S-type granites or A-type granites, as described below.
