Unit 1.7: Periodic Trends
Apply Coulomb’s Law and atomic structure features to compare atomic properties between two elements.
Explain why fluorine has a smaller atomic radius than oxygen.
Show Answer
Use periodicity to predict or estimate values of properties of elements.
Which element has a higher first ionization energy: Na or K?
Show Answer
Sodium (Na) is higher in group 1 than Potassium (K). It will therefore have a smaller atomic radius and a higher first ionization energy.
