WebIt needs two electrons to make it stable as 8 electrons in its valence shells. This makes oxygen a O −2 anion. Ionic bond form when the charges between the metal cation and non-metal anion are equal and opposite. This means that two Li +2 cations will balance with one O −2 anions. The ionic formula for Lithium Oxide is Li 2O. WebCalcium oxide molecules contain one calcium cation (which holds a charge of +2) and one oxygen anion (which holds a charge of -2). The structure of calcium oxide is illustrated below. Thus, it can be understood that calcium oxide is an ionic compound featuring an ionic bond between calcium and oxygen. Lime Water Formula WebWater softeners utilize exchange resins which exchange one ionic species for another. In water treatment, the hard water mineral ions calcium (Ca +2) and magnesium (Mg +2) are exchanged for sodium (Na +) ions. As this is an exchange, the ionic activity or total dissolved solids (conductivity) remains nearly constant. desk with inset glass
