This energy diagram shows the allowed energy levels of an electron in a certain atom

This energy diagram shows the allowed energy levels of an electron in a certain atom. (Note: the SI prefix 'zepto' means 10^-21. You can find the meaning of any SI prefix in the ALEKS Data tab.)

Use this diagram to complete the table below.

What is the energy of the electron in the ground state?

What is the energy of the electron in the first excited state?

If the electron makes the transition shown by the red arrow, from B to C, will a photon be absorbed or emitted?

Calculate the wavelength of the photon that would be absorbed or emitted. Round your answer to 3 significant digits.

Expert Solution

This question is solved by using the given energy diagram, when the electron moves from a lower energy level to a higher energy level, it is the absorption of energy.
