a Current, modern IUPAC group number.
b The noble gases had not yet been discovered at the time of Mendeleev's original table. Later (1902), Mendeleev accepted the evidence for the existence of the noble gases, and placed them in a separate "group 0".
c Hydrogen (H), while placed in column 1, is not considered to be in the group alkali metals.
d Group 3: Depending on the source, this group includes lutetium (Lu) and lawrencium (Lr), or lanthanum (La) and actinium (Ac), or the whole set of 15 lanthanides and 15 actinides, as the entries below scandium and yttrium.
e This group name is not recommended by IUPAC.
