1. lanthanidenoun

   Any of the 14 rare earth elements from cerium (or from lanthanum) to lutetium in the periodic table; because their outermost orbitals are empty, they have very similar chemistry; below them are the actinides.

1. lanthanide

   Lanthanides, also known as rare earth metals, are a group of 15 chemical elements in the periodic table, specifically ranging from lanthanum (atomic number 57) through lutetium (atomic number 71). They are characterized by similar properties, including high melting points, high boiling points, and variable metallic properties. The term "lanthanide" derives from the first element in the series, lanthanum. These elements are widely used in various industries due to their unique magnetic, luminescent, and electrochemical properties.

1. Lanthanide

   The lanthanide or lanthanoid chemical elements comprises the fifteen metallic chemical elements with atomic numbers 57 through 71, from lanthanum through lutetium. These fifteen lanthanide elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth elements. The informal chemical symbol Ln is used in general discussions of lanthanide chemistry to refer to any lanthanide. All but one of the lanthanides are f-block elements, corresponding to the filling of the 4f electron shell; lutetium, a d-block element, is also generally considered to be a lanthanide due to its chemical similarities with the other fourteen. All lanthanide elements form trivalent cations, Ln3+, whose chemistry is largely determined by the ionic radius, which decreases steadily from lanthanum to lutetium. The lanthanide elements are the group of elements with atomic number increasing from 57 to 71. They are termed lanthanide because the lighter elements in the series are chemically similar to lanthanum. Strictly speaking, both lanthanum and lutetium have been labeled as group 3 elements, because they both have a single valence electron in the d shell. However, both elements are often included in any general discussion of the chemistry of the lanthanide elements.
