Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ''periodic law'' in their properties, in which elements in the same column (group) have similar properties.
The known elements are arranged in order of increasing Z in the periodic table (Figure (PageIndex{1})). The rationale for the peculiar format of the periodic table is explained later. E ach element is assigned a unique one-, two-, or three-letter symbol. The names
