... A chemical group/family is a vertical column of elements that have similar physical and chemical properties. On the periodic table there are 18 vertical groups. Column 1: alkali metals Column 2: alkaline earth metals Column 3-11: transition metals Column 17: halogens Column 18: noble gases/inert gas ...
