What is the lanthanide series?
ChemistryPeriodic table
Quick Answer
The lanthanides are a group of 15 metallic elements from lanthanum to lutetium. They are often called the rare earth elements, though many are not especially rare in the crust.
The Full Story
The lanthanide series occupies a separate row below the main body of the periodic table to keep the chart compact. These elements have similar chemistry because they fill the 4f electron shell. They are important in magnets, lasers, phosphors, catalysts, and modern electronics. Despite the name “rare earths,” several lanthanides are more abundant than metals such as silver. Their chemistry was clarified over many decades as spectroscopy and atomic theory advanced.
Key Facts
1.The lanthanides run from lanthanum to lutetium
