CHEM 219 Module 2 problem set Questions with Verified 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? - ANS - Hafnium 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 succ...

ABCTE -The Solar System and the UniverseTools of the Astronomer - correct answer The basic tool that astronomers use to study celestial objects is the telescope. People tend to be most familiar with optical telescopes, but astronomers use telescopes that span the entire electromagnetic spectrum. Radio Waves - correct answer Radio waves are the longest waves of the electromagnetic spectrum. We use radio waves to broadcast radio, TV, and cellular phone signals. Radio waves are also used to pe...
