The effect of ion polarization on the properties of compounds
Time of Update: 2021-06-18
1. The effect of ion polarization on the physical properties of compoundsIonic polarization causes the bond type of the compound to transition from ionic bond to covalent bond, which inevitably reduces the solubility of the compound and lowers its melting and boiling points .

The effect of ion polarization on the bond type and crystal structure of compounds
Time of Update: 2021-06-18
2. Ion polarization affects the type of crystal structureIon polarization increases the electron cloud overlap between the positive and negative ions in the compound, and the crystal structure transitions from a high-coordination structure to a low-coordination structure .
