When students in chemistry begin to learn about Periodic trends, important concepts such as atomic instability and the desire for atoms to become isoelectronic with the nearest noble gas arise. Students generally understand what an ion is, but they often struggle to comprehend how ionization occurs. This two-part lesson will help students reinforce key concepts such as ionization, cations, anions, parent atoms, isoelectronic states as well as their relation to each other. Mastery of the aforementioned concepts will help students understand the rise of electrostatic forces of attraction responsible for ionic bonds in crystal lattices. The first lesson is a fill in the blank activity two pages long. There are four paragraphs and I offer a word/term bank for each one. The second lesson is a two page isoelectronic state identification and analysis sheet. Four pages of answer keys are included.
