The actinides (or actinoids) family contain the following elements: actinium, thorium, protactinium, uranium, neptunium, plutonium, americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium, lawrentium; beginning with neptunium the elements are only artificially obtained.
Because plutonium has some similar properties with the other members of the actinoids family.
