this boronic thing (negative ion, really) they _might have seen_ has 241 (valence) electrons.. You'd expect a nice 240 given the symmetry, not a prime number

this boronic thing (negative ion, really) they _might have seen_ has 241 (valence) electrons.. You'd expect a nice 240 given the symmetry, not a prime number Or maybe a less baity reason is those hints of B_80^- have captured H+ "nuclei", turning into almolecular atoms! Not oxyboronic at all
