Atomic radii - Study guides, Class notes & Summaries

Chem 219: Exam 2 Questions With 100% Correct Answers The atomic radii of zirconium (Zr) and hafnium (Hf) are nearly the same despite the fact that hafnium has 32 more protons and electrons. Which of the following bests explains this phenomenon? - answerHafnium contains electrons in the 4f orbitals. These 4f electrons do not effectively shield the higher nuclear charge and thus Zeff is higher than might be otherwise expected. Which of the following is true concerning successive ionizations...
