The answer is that electronic configurations of atoms are not sufficient to settle this question, just as they do not fully settle the question of where hydrogen and helium should be placed in the periodic table, a point I will return to later. (rsc.org)
The subject of the retracted Nature paper was purported to be such a material, made of hydrogen, lutetium and nitrogen. (sciencenewshubb.com)
The basis for super-hydrides was laid out in 2004, when the late theoretical physicist Neil Ashcroft predicted that certain elements would form compounds with hydrogen that could superconduct at much higher temperatures than could any other material, if put under enough pressure to force the hydrogen atoms closer together. (sciencenewshubb.com)
According to Ashcroft's theory, the proximity of the hydrogen atoms would increase the frequency of mechanical vibrations, which would enable the material to get warmer while retaining its superconductivity. (sciencenewshubb.com)
Advances in carrying out high-pressure experiments on tiny samples inside a diamond anvil - and measuring their outcomes - led to a breakthrough in 2015, when physicist Mikhail Eremets at the Max Planck Institute for Chemistry in Mainz, Germany, and his collaborators first demonstrated superconductivity in a super-hydride , hydrogen sulfide.

The array of donor atoms directly attached to the central metal is referred to as the first coordination sphere, while a second coordination sphere consists of molecules and ions interacting in various ways with the first coordination sphere. (researchoutreach.org)

Despite their name, the rare earth elements (REEs) are an abundant group of metallic elements (grouped with the actinides near the bottom of the periodic table) comprised of 15 lanthanides (lanthanum-lutetium), scandium, and yttrium. (researchoutreach.org)

A fruitful method that has been employed to sequester and identify actinides, especially in selective sequestration even in the presence of lanthanides, has been to incorporate softer nitrogen donor atoms and pair them with phenolate donors. (auburn.edu)

However, on a significant number of more recent periodic tables you will find lutetium and lawrencium classified as transition metals and placed directly underneath scandium and yttrium in group 3 of the periodic table. (rsc.org)
The elements placed directly under scandium and yttrium in older periodic tables are lanthanum and actinium, but on the basis of electronic configurations lutetium and lawrencium have as much right to occupy these two places. (rsc.org)
If one tries to construct the long-form table it is lutetium and lawrencium that fall more naturally under scandium and yttrium in group 3. (rsc.org)
But this fact has not convinced everyone and nor have the numerous chemical and physical similarities that exist when lutetium and lawrencium are considered as homologues of scandium and yttrium. (rsc.org)
Because scandium (Sc), yttrium (Y), and lanthanum (La) actually do not form compounds analogous to those of the other transition elements and because their chemistry is quite homologous to that of the lanthanoids (previously known as lanthanides), they are often excluded from the group of transition elements.
