    Chemistry S2.1.1 The Nature of Ionic Bonds

    Learning Objectives Part 1: The Nature of Ionic Bond Explanation of the formation of ionic bond How to calculate effective nuclear charge For example: Lithium has 1 valence electron and 2 inner electron. The nuclear charge is +3. Therefore the effective nuclear charge experienced by the valence electron is +3 – 2 = +1 Part…
