a Current, modern IUPAC group number.
b While not included in Mendeleev's original table, Mendeleev later (1902) 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, lutetium (Lu) and lawrencium (Lr) may be included; lanthanum (La) and actinium (Ac) may be included; the f-block (with 14 lanthanides and 14 actinides) may be included.
e This group name is not recommended by IUPAC.
