Lanthanides Properties

Lanthanides Properties of Element Groups

The lanthanides are a group of 15 chemical elements, with atomic numbers 57 through 71. All of these elements have one valence electron in the 5d shell. The elements share properties in common with the first element in the group -- lanthanum. The lanthanides are reactive, silver-colored metals.

Lanthanides Properties Of The Lanthanides Compounds

Compounds of lanthanides with the element fluorine (lanthanide fluorides), however, are insoluble. Adding fluoride ions to a solution of tripositive lanthanide ions can generally be used as a characteristic test for the presence of the lanthanides. Likewise, lanthanide oxalates (oxalate is the negative ion C z O 4-2) have low solubility.

Actinides (Actinide Series) Element Properties

The actinides successively fill the 5f sublevel. 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 actinides (An) may be prepared by reduction of AnF3 or AnF4 with vapors of Li, Mg, Ca, or Ba at 1100-1400 C.

Lanthanides and Actinides Introduction to Chemistry

The lanthanides and actinides form a group that appears almost disconnected from the rest of the periodic table. This is the f block of elements, known as the inner transition series. This is due to the proper numerical position between Groups 2 and 3 of the transition metals.

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.
