Detailed explanation-2: -Chemical symbol While the symbol is often a contraction of the element’s name, it may sometimes not match the element’s name when the symbol is based on non-English words; examples include “Pb” for lead (from plumbum in Latin) or “W” for tungsten (from Wolfram in German).

Detailed explanation-3: -Elements have been named after a number of things including their attributes, the compound or ore from which they were isolated, how they were discovered or obtained, mythological figures, places, and famous people. Some elements have descriptive names based on an attribute of the element.
