Lanthanides

Subject: Chemistry

Book: General Chemistry

The lanthanides (atomic numbers 57–71) are a series of soft, reactive metals typically found together in nature and often challenging to separate. They include elements like cerium, neodymium, and europium. These metals are used in high-tech applications such as magnets, lasers, and phosphors in lighting. Their similar chemical properties arise because they fill the 4f electron orbital, leading to subtle variations in reactivity and ionic radii.
