![]() The periodic table is a chart that organizes the elements by increasing atomic number and their chemical and physical properties (see article History of the Periodic table of elements). We can list elements in order of increasing atomic number but it wouldn't be a periodic table any more. Organization of chemical elements in alphabetical order by their names (or symbols) doesn't tell us anything about their properties but it is useful when searching for an element. ![]() Why is the periodic table shaped like it is?
