Lithium clue for planet-hunters
Physicists know the Sun's upper layers as viewed today do not convect deeply enough to take any lithium to a location that is sufficiently hot to burn the element. This suggests mixing conditions must have been different in the past. The...

More on Lithium
Description from Wikipedia:
Lithium (pronounced: /ˈlɪθiəm/) is a soft, silver-white metal that belongs to the alkali metal group of chemical elements. It is represented by the symbol Li and has an atomic number of 3. Under standard conditions it is the lightest metal and the least dense solid element. Like all alkali metals, lithium is highly reactive, corroding quickly in moist air to form a black tarnish. For this reason, lithium metal is typically stored under the cover of oil. When cut open, lithium exhibits a metallic luster, but contact with oxygen quickly turns it back to a dull silvery gray color. Lithium in its elemental state is highly flammable.
According to theory, lithium was one of the few elements synthesized in the Big Bang. Since its current estimated abundance in the universe is vastly less than that predicted by theory, the processes by which new lithium is created and destroyed, and the true value of its abundance, continue to be active matters of study in astronomy. The nuclei of lithium are relatively fragile: the two stable lithium isotopes found in nature have lower binding energies per nucleon than any other stable compound nuclides, save deuterium, and He. Though very light in atomic weight, lithium is less common in the solar system than 25 of the first 32 chemical elements.
Due to its high reactivity it only appears naturally in the form of compounds. Lithium occurs in a number of pegmatitic minerals, but is also commonly obtained from brines and clays. On a commercial scale, lithium metal is isolated electrolytically from a mixture of lithium chloride and potassium chloride.
