The chemical symbol for lithium is "Li." In the periodic table, each element is represented by a one- or two-letter symbol, which is derived from its name. For lithium, the symbol "Li" comes directly from the first two letters of its name in English. This symbol is widely recognized in chemistry, and it is used to denote lithium in chemical equations, reactions, and when referring to compounds containing lithium. Other options, such as "Ls," "Lt," and "L," do not correspond with the established scientific notation for lithium. Each of these alternatives either does not adhere to the standard naming conventions for elements or refers to other letters rather than the correct representation for lithium.
