Corrigendum: Atomic and Ionic Radii of Elements 1–96

The previously reported radii for 8 elements are corrected here. Incorrect electronic configurations of five elements Fe, Co, Ni, Tc, and Ir, resulted in approximately 0.1 Å underestimates of their radii. These larger corrections originate from previously considering the s1 instead of the s2 valence configurations. For example, for Fe, we had calculated the configuration 4s13d7 instead of the correct 4s23d6. We also report minor corrections on the order of ≈0.01Å for the three elements Zr, Th, and Np. These have their origin with the spin state, quality of the orbitals, and the orbital occupancy (for Np 7s25f5 vs. the correct 7s25f46d1), respectively. These changes do not affect any conclusions in the original paper. In contrast, these corrections improve the already good agreement with Alvarez's crystallographic data. A list of the changes is given in the Table 1 below; these replace the incorrect values shown in Figures 2, 3, 5 and 6 in the manuscript. A revised version of Figure 1 is also provided below.
