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.

Describe the relationship between the frequency, wavelength, and velocity (speed) of a wave. - AnswerThe more times the wave is passing through a point in space = a higher frequency, the higher frequency 
creates a smaller wavelength, which is why the smallest wave is a gamma wave, it has the highest 
frequency and the shortest distance between waves, the velocity can be measured in m/s and is 
composed of frequency and wavelength 
Calculate any one (frequency, wavelength, or velocity) given the...
