A Group 3 element is the series of elements in group 3 (IUPAC style) of the periodic table, which consists of

All of these elements are classed in Group 3 because their outer shell holds three electrons. Scandium, yttrium, and the lanthanides (except promethium) can all be found naturally, albeit at very low levels in the Earth's crust, and are collectively called rare-earth metals. Promethium, actinium, protactinium, neptunium, and americium through lawrencium can only be produced in the laboratory and have not been found in nature.
