Study of the properties of the actinides is hampered by their radioactive instability. To complete our look at the periodic table there is one more group we have to consider. They include naturally occurring elements of thorium, protactinium and uranium and eleven.
(inorganic chemistry) any of the 14 radioactive elements of the periodic table that are positioned under the lanthanides to which they have similar chemistry.
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. The following article is from the great soviet it might be outdated or ideologically biased. These elements are also called the actinide elements.
