The periodic table is the most powerful tool chemists, have for organizing chemical information. Without it, chemistry would be a chaotic, confusing jumble of seemingly random observations. What makes the periodic table really invaluable is, its use as a predictive tool. You can predict a lot about the chemical behavior of an element. If you know where it is on the periodic table. Each element is represented by one square on the periodic table. With a one or two-letter chemical symbol. Many of the chemical symbols are derived from the English name for the element. But some come from other languages.
For example, the symbol for silver is Ag, from the Latin word argentum. The symbol for lead is Pb, from the Latin word plumbum. Above the chemical symbol is the atomic number of the element. Below the symbol are the full name of the element and its atomic mass.
