NettetAt the stability limit the cation is touching all the anions and the anions are just touching at their edges (radius ratio = 0.155). For radius ratios greater than 0.155, the compound may be stable. The table below gives the relation between radius ratio and coordination number, which may be obtained from a simple geometrical proof.

Nettet17. feb. 2024 · We discuss each Pauling rule separately, stressing their limits and range of application in terms of chemistries and structures. We conclude that only 13 % of the oxides simultaneously satisfy the last four rules, indicating a much lower predictive power than expected. Introduction Nettet• Atomic radius decreases within a period of the periodic system (horizontal from left to right). • Ionisation of an atom (electron donation or reception) changes its radius. • If valence electrons are donated (cation), then the remaining electrons will be stronger attracted to the nucleus and the ionic radius decreases highland apartments columbus ohio
