A color-coded periodic table of the elements displays each element's symbol and atomic number, with categories such as alkali metals, noble gases, halogens, transition metals, and actinoid elements distinguished by different background colors. — alkali metal Modern version of the periodic table of the elements (printable).

Sodium and potassium are highly reactive elements that are typically found in nature combined with other elements in various minerals.1

Sodium Minerals

Sodium is a major component of many minerals, including:
* Halite: Also known as common salt (NaCl).12
* Carbonates: Including natron, trona, and thermonatrite.2
* Sulfates: Such as mirabilite, thenardite, and sodium sulfate.32
* Borates: Including borax.3
* Nitrates: Such as Chile saltpetre (sodium nitrate).2

Potassium Minerals

Potassium is found in various geological deposits, often in ancient lake beds and seabeds:4
* Sylvite: Potassium chloride (KCl).14
* Carnallite: A potassium-magnesium chloride.14
* Polyhalite: A complex sulfate mineral.4
* Langbeinite: A potassium-magnesium sulfate.4
* Silicates: Potassium is also present in insoluble minerals such as muscovite and orthoclase feldspar, which are common in igneous rocks and shale.4
