The presence of this many lone pairs results in triiodide's linear structure according to VSEPR
A group with this denticity is found on the chelex 100 resin used for ion exchange chromatography and extracting metal ions. The ligand IDA can bind up to this many sites, as can POCOP, a member of the cyclometallation cockblocking class of pincer ligands. This is the number of ligands found on complexes that racemize through the Ray-Dutt or Bailar twists. Octahedral complexes with less than or equal to this number of d electrons do not distinguish between high and low spin configurations because there are this many (*) t2g orbitals. Ligands with this denticity can bind either facially or meridionally. There are this many bridges between the "caps" of a cryptand. The presence of this many lone pairs results in triiodide's linear structure according to VSEPR ["vesper"] theory. For 10 points, name this number of oxygens in the nitrate and carbonate ions, whose geometries are trigonal planar.
