lanthanides properties

Lanthanide - Wikipedia

Many actinide metals have properties of both d block and f block elements. Actinides display several valence states (typically more than the lanthanides). Most are prone to hybridization.

The lanthanide contraction is the greater-than-expected decrease in ionic radii of the elements in the lanthanide series from atomic number 57, lanthanum, to 71, lutetium, which results in smaller than otherwise expected ionic radii for the subsequent elements starting with 72, hafnium.

Lanthanide contraction - Wikipedia

The lanthanides are the elements with atomic numbers from 57 to 71. These 15 metals (along with scandium and yttrium) are often called the rare earth elements. They are all silvery-white metals which are often found in the same ores. They are called the lanthanides because they exhibit similar chemical properties to lanthanum, the first element in the group.
