Lithium is a chemical element, number 3 on the periodic table. It the lightest alkali metal on the table, with an atomic weight of 6.941 units (1 unit roughly equals the weight of a proton or neutron).
A special crystal form of this element has a structure resembling quartz and was considered sufficient for use in early warp cores. (TOS: "Where No Man Has Gone Before", TOS: "Mudd's Women")
However, dilithium, a derivative of lithium, is now the standard in all warp technology.
Lithium was used to build computer chips before isolinear components were invented.
- Lithium was originally used as the basis of warp technology. However, lithium is a real element with known properties. Dilithium was invented to allow for a fuel material with unknown properties.
