About Group no. of periodic table!

(1/1)

Winga:
Is it the previous version of group no. (e.g. IA, IIA, IIIB, IVB...) now changed to 1 - 18?

Mitch:
IUPAC has now changed the periodic table so that the Group numberings will read fromm 1-18

dexangeles:

the1A-8A numbering is a quick reference, ya know what I mean jellybean  :-\

Donaldson Tan:
