LITHIUM CARBONATE BATTERY

Facts, pictures, stories about the element Lithium in the Periodic Table Lithium is an alkali metal, and like all the other alkali metals, it reacts spontaneously with water, liberating hydrogen gas. The farther down you go in the periodic table, the more reactive the alkali metals become, and as the uppermost one lithium is the least reactive. But it's still a fairly vigorous reaction, and lithium can catch fire spontaneously on a humid day. Lithium is amazingly light, only half the density of water. It would be a great metal for making airplanes out of if it weren't so soft and didn't explode on rainy days. Instead it's used in high-quality batteries and as a medication for mood disorders, because dissolved as lithium ions, it moderates nerve impulses in a way that, for poorly understood reasons, moderates mood swings (see the pills below for more on this).
