The Full Story
The lanthanides are commonly displayed in a detached row below the main body of the periodic table to keep the chart compact. This series includes 15 elements from lanthanum (57) to lutetium (71). They are often grouped together because they share very similar chemical properties, especially the 4f electron arrangement. The separate layout is a practical design choice, not a sign that they are outside the periodic table.
