Since Lambda for an oxide is proportional to the degree of negative charge borne by the oxide-(-II) atom or ion, it follows that optical basicity should go hand-in-hand with the ionic/covalent nature of the cation-oxide-(-II) bonding. Unfortunately, this assumption produces many anomalies ...
Give the formula for calcium chloride. Is this compound ionic or covalent? Calcium forms ions with a charge of +2. Iodine forms ions with a charge of -1. Which of the following would represent an ionic compound composed of Calcium and Iodide ions? a. CaI...
