What do symbols stand for on the periodic table?
The periodic table is a classification system for the elements. The symbols are abbreviations of the origins of the word for each element. For example, the origin of lead’s symbol, Pb, is the Latin word ‘plumbum’ meaning ‘liquid silver’. The number above the symbol is the atomic mass (or atomic weight).
What is labeled on the periodic table?
