An extended periodic table theorizes about chemical elements beyond those currently known and proven. The element with the highest atomic number known is oganesson (Z = 118), which completes the seventh period (row) in the periodic table. All elements in the eighth period and beyond thus remain purely hypothetical.

A block of the periodic table is a set of elements unified by the atomic orbitals their valence electrons or vacancies lie in. [1] The term seems to have been first used by Charles Janet. [2] Each block is named after its characteristic orbital: s-block, p-block, d-block, f-block and g-block.

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.

Extended periodic table The template takes parameter number= (atomic number). When this number is >118, the template expands with periods 8 and above, adding the (predicted) elements with atomic number >119.
