   What elements are in Group 3?

   • The periodic table appearing on the IUPAC web site (Fig. 1) depicts the first two elements of Group 3 as being scandium and yttrium. Below the box for yttrium is found one box for the lanthanoids and below that one box for the actinoids.

   How many interlocking arguments are there for lanthanum in Group 3?

   • Continuing the theme, a series of ten interlocking arguments, in the context of a chemistry-based periodic table, are presented in support of lanthanum in Group 3. In so doing, I seek to demonstrate a new way of thinking about this matter. The last of my ten arguments is recast as a twenty-word categorical philosophical (viewpoint-based) statement.

   Why is aluminium shifted to Group 3?

   • Aluminium has been shifted to Group 3, for this purpose. An isodiagonal relationship can be seen along calcium-yttrium-cerium With lutetium in Group 3 (Fig. 16), isodiagonality is lost and replaced with the diagonal sequence Ca–Y–Hf. Calcium and yttrium are strongly basic; hafnium is amphoteric.

   How many chemistry books have Group 3?

   • A survey reported by the task force, of 193 chemistry books published during the 1970s to the 2010s, found that 130 books (67%) had Group 3 as Sc–Y–La–Ac; 33 (17%) as Sc–Y-*-**; and 30 (16%) as Sc–Y–Lu–Lr. The project further notes the question is of considerable importance for chemists and physicists, but does not elaborate.

   Group 2 metals show similar trends in reactivity to Group 1 metals as you go down the group. Magnesium is another Group 2 metal. Explain why, in terms of atomic structure, magnesium reacts in a similar way to calcium with element Z but it is less reactive than calcium.
