NationMaster - Encyclopedia: Inner transition element

The inner transition elements comprise the elements of the f-block of the periodic table. This block is often drawn separated from the rest of the periodic table, and traditionally located immediately below it. There are two series of inner transition elements, the actinides and the lanthanides, each named after the beginning element of the row.

See also transition metals, which describes the d-block.

Transition metal Summary (1768 words)
	Transition elements, or metals, are a category of materials in the periodic table that are set apart from the "major group" or "A series" elements by their ability to use either the penultimate and outermost electron shells to bond with other substances.
	The (loosely defined) transition metals are the 40 chemical elements 21 to 30, 39 to 48, 71 to 80, and 103 to 112.
	Transition elements tend to have high tensile strength, density and melting and boiling points.
