| 1. | Group 12 elements are all soft, diamagnetic, divalent metals.
|
| 2. | This increases the reabsorption of divalent cations by secondary active transport.
|
| 3. | The DNA cleavage event also requires the divalent metal cation magnesium.
|
| 4. | Divalent manganese may also substitute for magnesium in the crystal structure.
|
| 5. | The metal is divalent and has a noticeably high volatility.
|
| 6. | Another divalent ion, Mg2 +, causes further precipitation of hyalin.
|
| 7. | Many of these divalent complexes are sensitive to aerial oxidation.
|
| 8. | Divalent manganese ( Mn ) may substitute for some of the magnesium.
|
| 9. | Certainly, MgO'could'be either monovalent or divalent ions.
|
| 10. | It is believed to exhibit resonance between its tetravalent and divalent carbon forms.
