WebJun 7, 2024 · Ionic radii depend on oxidation state (higher charge => smaller cation size, larger anion size) We can build up a table of ionic radii by assuming that the bond length is the sum of the radii (r + + r -) if the ions are in contact in the crystal. Consider for example the compounds MgX and MnX, where X = O, S, Se. WebJan 2, 2024 · Representing the crystal structure of inorganic compounds with 2D images allows CNN to learn ...
