Bold text in Periodic Table 1871
Italic text in Periodic Table 1906 (the last by Mendeleev)
Regular text (not bold) added after 1906
      begin–end of 1871 Reihe
Ga Element predicted, later proven correct within Mendeleev's lifetime and added by him
 (Tc) Element predicted, later proven correct posthumously
Element projected, but not predicted
strikethrough Element predicted, later proven wrong due to
– not an element ("?Di"), or
–wrong position ("[Ac]") because of non-recognition of separate rare earth series
[ ] Added or changed after 1871
Cu(1st) × / (Cu)(2nd) Element mentioned twice: in Gruppe VIII and I. The 2nd mentioning survived, Gruppe/group VIII was reduced from four columns to three (×)
