Test Bank – Ionic and Covalent Bonding: Solutions to Exercises (Updated 2025) SOLUTIONS TO EXERCISES 9.1. 9.2. The Lewis symbol for oxygen is : . . . O . and the Lewis symbol for magnesium is . Mg . . The magnesium atom loses two electrons, and the oxygen atom accepts two electrons. You can represent this electron transfer as follows: The electron configuration of the Ca atom is [Ar]4s2. By losing two electrons, the atom assumes a 2+ charge and the argon confi...
