An Experimental Measurement of the Energy Levels of the Hydrogen

question 13

Multiple Choice

An experimental measurement of the energy levels of the hydrogen molecule H₂ shows that the energy levels are evenly spaced and separated by about 9 * 10^-20 J.A reasonable model of one of the hydrogen atoms would then seem to be that of a hydrogen atom in a simple harmonic oscillator potential.Assuming that the hydrogen atom is attached by a spring with a spring constant k to the molecule,what is the spring constant k?

• A)2.0 N/m
• B)700 N/m
• C)950 N/m
• D)1200 N/m
• E)2600 N/m
