   Elements within the same group share the same number of valence electrons. The number of valence electrons depends on the octet rule. For example, elements in group 1 have 1 valence electron, elements in groups 3-12 have a variable number of valence electrons, and elements in group 17 have 7 valence electrons. The lanthanides and actinides, located...

   Sometimes chemists classify element groups according to shared properties, which do not strictly adhere to individual columns. These groups go by the names alkali metals, alkaline earth metals, transition metals, basic metals, nonmetals, halogens, noble gases, lanthanides, and actinides. Under this system, hydrogen is a nonmetal. The nonmetals, hal...

   Elements within a period share the same number of electron shells and the same highest unexcited electron energy level. Elements within a period display periodic table trends, moving from left to right, involving atomic and ionic radius, electronegativity, There are seven element periods. Some periods contain more elements than others because the n...

   Why are the elements in the two bottom rows included in Group 3?

   • The elements in the two bottom rows of the periodic table are also included in these groups. They are placed in the two separate rows at the bottom because they show few different properties. Actually, the elements in the bottom rows are the extension of group 3 only. So they are included in group 3.

   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.

   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.
