The History of Lithium (Written October 2007). The following is a simplification of an excellent history by Dr. Robert Howland. Lithium was first discovered as a chemical element in 1817.By the mid-1800s, there was great interest in “urate imbalances”, which were thought to explain a variety of diseases, including mania and depression.

Potassium: the essentials Potassium is an essential constituent for plant growth and it is found in most soils. It is also a vital element in the human diet. Potassium is never found free in nature, but is obtained by electrolysis of the chloride or hydroxide, much in the same manner as prepared by Davy.

Potassium Potassium is a chemical element with symbol K (from Neo-Latin kalium) and atomic number 19. It was first isolated from potash, the ashes of plants, from which its name derives. In the periodic table, potassium is one of the alkali metals. All of the alkali metals have a single valence electron in the outer electron shell, which is easily removed to create an ion with a positive charge – a cation, which combines with anions to form salts. Potassium in nature occurs only in ionic salts.

Helium: the essentials In 1895, Sir William Ramsay discovered helium after treating cleveite, a uranium mineral, with mineral acids. Ramsey sent samples of the gas to Sir William Crookes and Sir Norman Lockyer who identified helium. It was discovered independently in clevite by Cleve and Langley at about the same time.elium is the second most abundant element in the universe. It is very common in the hotter stars. It is an important component in the proton-proton reaction and the carbon cycle in stars.

- In 1807, Sir Humphrey Davy, an English chemist, discovered how to extract and isolate sodium from its compounds. Since sodium doesn't appear by itself in nature, this discovery lead to better understanding of sodium compounds, such as sodium chloride, which is the primary factor in the salinity of the oceans.

- The lithosphere (outer layers) of the earth has been estimated to be 2.59 percent Potassium, of which about 0.01167 percent is 40K. An approximately total of 5 x 1021 grams of 40K in the earth of which 11.2 percent could eventually decay into 40Ar. 40K has a half life of 1.26 billion years (1.26 x 109). To generate the amount of 40Ar in the atmosphere would require in round numbers 250 million years.

- A pure, but tiny, amount of the metal was isolated in 1808 by Humphry Davy by the electrolysis of magnesium oxide. However, it was the French scientist, Antoine-Alexandre-Brutus Bussy who made a sizeable amount of the metal in 1831 by reacting magnesium chloride with potassium, and he then studied its properties.

Elements for Kids Where did potassium get its name? Potassium gets its name from the salt potash from which potassium was first isolated. The K symbol for the element comes from the Latin word kalium, which means potash. Isotopes There are three isotopes of potassium that occur naturally: K-39, 40, and 41. The majority (93%) of potassium found in nature is K-39.

Potassium iodide Potassium iodide is an inorganic compound with the chemical formula K I. This white salt is the most commercially significant iodide compound, with approximately 37,000 tons produced in 1985. It is less hygroscopic (absorbs water less readily) than sodium iodide, making it easier to work with. Potassium iodide occurs naturally in kelp.

Humphry Davy Chlorine was discovered in 1774 by Swedish chemist Carl Wilhelm Scheele, who called it dephlogisticated marine acid (see phlogiston theory) and mistakenly thought it contained oxygen. Davy showed that the acid of Scheele's substance, called at the time oxymuriatic acid, contained no oxygen.

Potassium: historical information Until the 18th century no distinction was made between potassium and sodium. This was because early chemists did not recognise that vegetable alkali (K 2 CO 3, potassium carbonate, coming from deposits in the earth) and mineral alkali (Na 2 CO 3, sodium carbonate, derived from wood ashes) are distinct from each other.
