This very soluble salt has been leached into the oceans over the lifetime of the planet, but many salt beds or ‘lakes’ are found where ancient seas have evaporated. This was because early chemists did not recognise that "mineral alkali" (Na 2 CO 3, sodium carbonate, coming from deposits in the earth) and "vegetable alkali" (K 2 CO 3, potassium carbonate, derived from wood ashes) are distinct from each other.Eventually a distinction was made. Sodium is the fourth most abundant element on earth, comprising about 2.6% of the earth's crust; it is the most abundant of the alkali group of metals. He also discovered potassium in the same year again by using electrolysis. Because sodium is extremely reactive, it never occurs in the free state in Earth’s crust. He was the son of a chemist from Penzance Cornwall. Sodium’s low density allows it to float on water, although placing a large quantity of sodium in water would not be a good idea. Shortly after, Thenard and Gay-Lussac isolated sodium by reducing sodium hydroxide with iron metal at high temperatures. This method is much cheaper than that of electrolyzing sodium hydroxide, as was used several years ago. This discovery, later, led to the knowledge of extracting sodium chloride.
