On the older style of Periodic Table, you will notice that the groups are labelled Group I, Group II, etc with Roman Numerals. There were also A' s and B's assigned - for example above scandium was Group IIIA and above aluminum was IIIB. Therefore, the numbering system going across the table was Groups IA, IIA, IIIB, iVB, VB, VIB AND VIIB, VIII. Group VIIB was known as Group 7 or the Halogens. It is now know as group 17.
