The 2 bottom rows separated from the rest
The two rows at the bottom of the periodic table, known as the f-block, are separated to conserve space. They contain the lanthanides and actinides series of elements and would make the rest of the periodic table too wide if included. These rows are still part of the periodic table, but they are usually shown below as a separate section for convenience.
