Test Bank – Molecular Geometry and Chemical Bonding Theory: Solutions to Exercises (Updated 2025) SOLUTIONS TO EXERCISES 10.1. a. A Lewis structure of ClO3− is O O Cl O There are four electron pairs in a tetrahedral arrangement about the central atom. Three pairs are bonding, and one pair is nonbonding. The expected geometry is trigonal pyramidal. b. c. The Lewis structure of OF2 is

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...
