Elemental sodium was first isolated by Sir Humphry Davy in 1807 by passing an electric current through molten sodium hydroxide.
Although salt (sodium chloride) was long a part of civilization, sodium does not occur in a pure state because of reactions with oxygen and water.
the year 1807
Sir Humphrey Davy fired a small piece of KOH in a furnace and placed it on a platinum plate. He connected the plate to the negative terminal of an enormous battery made of 250 stacked cells made of 6" x 4" copper and zinc plates. The positive terminal was connected to a platinum wire and touched to the top of the KOH. The results were spectacular. Davy wrote: "The potash began to fuse at both its points of electrization. There was a violent effervescence at the upper surface; at the lower, or negative surface, there was no liberation of elastic fluid (gas), but small globules having a high metallic lustre, and being precisely similar in visible characters to quicksilver, appeared, some of which burnt with explosion and bright flame, as soon as they were formed, and others remained, and were merely tarnished, and finally covered with a white film which formed at their surfaces." According to Davy's brother, when Davy saw the globules of potassium metal break through the potash and burst into flame, "he could not contain his joy- he actually bounded about the room in ecstatic delight". A few days later, the experiment was repeated with sodium hydroxide, and sodium metal was discovered.
Humphrey Davy discovered Sodium in 1802 . He was the son of a chemist from Penzance Cornwall. He was head of the Royal Institution in London where he did most of his experiments.
