Actinium is a chemical element; it has symbol Ac and atomic number 89. It was first isolated by Friedrich Oskar Giesel in 1902, who gave it the name emanium; the element got its name by being wrongly identified with a substance André-Louis Debierne found in 1899 and called actinium.
Actinium is a radioactive metal. It is the third element in row 7 of the periodic table. It is considered often as the first of the actinides, a group of “inner transition metals”. Quite recently discovered, it has been a useful metal in laboratory research over the past century.
