An electron is excited from the n=1 ground state to the n=3 state in a hydrogen atom. Which of the
following statements are true? Correct the false statements to make them true.
It takes more energy to ionize (completely remove) the electron from n=3 than from the ground
state.
The electron is farther from the nucleus on average in the n=3 state than in the n=1 state.
The wavelength of light emitted if the electron drops from n=3 to n=2 will be shorter than the
wavelength of light emitted if the electron falls from n=3 to n=1.
The wavelength of light emitted when the electron returns to the ground state from n=3 will be the
same as the wavelength of light absorbed to go from n=1 to n=3.
For n=3, the electron is in the first excited state.

What wavelength of light is emitted when a hydrogen electron goes from n=3 to the ground state?

What is the wavelength of an electron (mass = 9.11x10-31kg) traveling at a speed of 1.0x107m/s?
