Periodic table of the chemical elements showing the most or more commonly named sets of elements (in periodic tables), and a traditional dividing line between metals and nonmetals. The f-block actually fits between groups 2 and 3 ; it is usually shown at the foot of the table to save horizontal space.
English: This pictorial periodic table is colorful, boring, and packed with information. In addition to the element's name, symbol, and atomic number, each element box has a drawing of one of the element's main human uses or natural occurrences. The table is color-coded to show the chemical groupings.

This happens to fill the whole periodic table in 7 rows (periods). Heavier elements (atomic number 119 and higher) are theoretically described, and start in period 8 (row 8). When these undiscovered elements are placed in the periodic table, it is called an extended periodic table.
