Students should be able to use Coulomb’s law to explain why ionization energies are always positive, why 2 nd ionization energy will always be greater than 1 st ionization energies. Chapter 8 part 1 Learning Objectives: 1. Recognize if a compound will be ionic or molecular. 2. What does it mean for an atoms or ions to be isoelectronic? What are the trends in sizes of ions? in sizes of isoelectronic ions? 3. Ionic bonding; what is the measure of the strength of an ionic bond? 4. What is lattice energy? How can one estimate the relative size of lattice energy of an ionic crystal? What experimental quantity can be used to compare lattice energies? Warm –up Questions Write the electron configurations for the following ions. Sb 3+ : In 3+ : Cu 2+ : Au + : Which neutral atom is isoelectronic with Mg 2+ , F – , Li + , S 2– ? What “trend” is noticeable here?...
