Group 3 of the Periodic Table

Group 3 of the periodic table has 2 elements: Scandium and Yttrium. Elements in a group have a similar last electron shell; the outer-shell pattern of all of them is ns², so they show similar chemical properties. Moving down a group, the number of shells and the atomic radius usually increase. The lanthanides and actinides form a separate f-block and are not included in this list.
