Where are lanthanides located on the periodic table?
In most wide form periodic tables, the lanthanides are in a row below the normal part of the table, with a reference showing that all the lanthanides correspond to period 6 column 3. Sometimes the lanthanide element with the lowest atomic number, lanthanum itself, is shown in the main table and the other lanthanides in a row below the main table.
Why are the lanthanides not in the sixth and seventh period in the periodic table?
You can find periodic tables where the lanthanides and actinides are drawn in the sixth and seventh period. This is actually where they belong on the periodic table. But drawing them there makes the table unmanageably wide. Placing them at the bottom and drawing arrows where they go keeps the table at a usable width. In the related links below, there is a link to an online periodic table that lets you see the lanthanides and actinides in their proper place. There is an option on that site to see the table 'wide.'
