Features of the Periodic Table Elements that have similar chemical properties are grouped in columns called groups (or families). As well as being nuered, some of these groups have names—for example, alkali metals (the first column of elements), alkaline earth metals (the second column of elements), halogens (the next-to-last column of elements), and noble gases (the last column of elements).
