The name sodium is derived from the Italian soda, a term applied in the Middle Ages to all alkalies; potassium comes from the French potasse, a name used for the residue left in the evaporation of aqueous solutions derived from wood ashes. While the German chemists Robert Bunsen and Gustav Kirchhoff were investigating the mineral waters in the Palatinate in 1860, they obtained a filtrate that was characterized by two lines in the blue region of its spectrum (the light emitted when the sample was inserted into a flame). 8 comments. When was Francium discovered? It soft and has a low density. Where are the alkali metals found in the periodic table? Which element is the most reactive? Therefore, they are ready to lose that one electron in ionic bonding with other elements. Hydrogen is a very reactive gas, and the alkali metals are even more reactive. 1939. The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure. LOGIN TO VIEW ANSWER. I have read that alkali metals are always found in nature as ions because they are so reactive towards water and oxygen, and I've also seen that the samples need to be stored under oil or in ampoules to prevent them from reacting.
