34+ Actinide Elements. Actinide series, a series of radioactive metallic elements in group 3 of the periodic table. Actinides concept the actinides (sometimes called actinoids) occupy the bottom line of the periodic table 1—a row of elements normally separated from the others.

This group holds its own unique position in any pictorial representation of the periodic table. The actinide series derives its name from the first element in the series. Along the actinide series, californium is the most relevant element of the second half due to its capability to emit neutrons.
Properties and reactions of the actinide series of elements.
(inorganic chemistry) any of the 14 radioactive elements of the periodic table that are positioned under the lanthanides to which they have similar chemistry. Start studying actinide series elements. They include naturally occurring elements of thorium, protactinium and uranium and eleven. Jump to navigation jump to search.
