And when he conducted further experiments, he noted that the behavior of the glass was relatively insensitive to other variables. It has the atomic number 19 and its atomic weight is 39.0983. It is used in fertilizers, as a salt substitute and to. Potassium chloride (KCl) is the most common potassium compound. Ellison observed an extremely strong link between the amount of potassium oxide and solubility. Potassium is a chemical element that is silvery-white in appearance. Potassium forms many important compounds. This means the atomic number of potassium is 19 and each potassium atom has 19 protons. Because he was building on research done by his advisor’s previous students, he was working with a base glass containing potassium oxide, aluminum oxide, and silicon oxide. Fast Facts: Potassium Potassium is element number 19. “When you’re trying to put something in the glass that the main glass components just don’t want in there, potassium is magical,” says Ellison.Įllison discovered this unusual behavior when he was conducting research for his Ph.D., examining how the solubility of zirconium oxide and titanium oxide varied with the composition of the glass. The carbonate was made by extracting wood. The addition of potassium also lowers the temperature at which silica devitrifies, which creates more flexibility. Well before potassium was recognized as an element, potassium carbonate was mixed with animal fat to make soap. If an element is difficult to dissolve, adding potassium will help by both increasing the solubility and the amount you can dissolve at a given temperature. People with the highest ratio of sodium to potassium. Gallium was discovered (1875) by French chemist Paul-Émile Lecoq de Boisbaudran, who observed its principal spectral lines while examining material separated from zinc blende. But what may be even more important for health is the relationship of sodium to potassium in the diet. It liquefies just above room temperature. One of the most interesting behaviors that Ellison observed is that potassium will make elements cooperate when they would normally conflict. gallium (Ga), chemical element, metal of main Group 13 (IIIa, or boron group) of the periodic table. In fact, it’s more of a mediator or facilitator. It is the nineteenth (19 th) on the periodic table of elements, and is seventh (7 th) most abundant element on Earth’s crust. Interesting Fun Facts Potassium is a soft solid and can be cut with a knife It does not occur in a free state in nature but it is an important part of many chemical compounds.
