The Periodic Table
The periodic table is an arrangement of the elements by increasing atomic number. Since the electrons add to energy levels in a regular pattern, elements with similar chemical properties tend to repeat themselves with a set period. This allows the table to be constructed such that elements that are most alike in chemical properties are in the same column.
