Actinides are typical metals and have properties of both the d-block and the f-block elements, but they are also radioactive. Elements are organised into blocks by the orbital type in which the outer electrons are found. In a theory of chemical bonding advanced by American chemist Gilbert N. Lewis and German chemist Walther Kossel in 1916, this octet of electrons was taken to be the most stable arrangement for the outermost shell of any atom. A: Click to see the answer. (Its oxidizing power means that it extracts electrons from other substances and confers on them a positive charge. Alternate titles: Group 0 element, Group 18 element, inert gas, rare gas.
