According to the Hume-Rothery rules, solid solutions only form when this quantity differs by less than 15% for solute and solvent. The lattice constant for BCC crystals is four over root three times this quantity. This quantity is smaller for cations than their corresponding
According to the Hume-Rothery rules, solid solutions only form when this quantity differs by less than 15% for solute and solvent. The lattice constant for BCC crystals is four over root three times this quantity. This quantity is smaller for cations than their corresponding neutral atoms. Because f electrons are very poor at shielding, this quantity does not change significantly across the lanthanide series. In general, this quantity decreases from left to right across a period and increases down a group. It equals 0.7 angstroms for carbon, half the length of a carbon-carbon bond. For 10 points, name this quantity measuring the "size" of an atom.
