Group Trends Ionic Radii MDCAT Quiz: Group Trends in Ionic Radii is a very important topic in the chemistry section of the MDCAT syllabus. Ionic radii are the sizes of an ion, which vary greatly between cations and anions. The changes in ionic radii within a group or across a period enable MDCAT students to analyze trends in ionic bonding, lattice energy, and compound stability. This topic is very important in interpreting periodic table properties and predicting chemical behaviors, so it is a high-yield area for MDCAT preparation.
