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.) 1200 energy (23) I 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 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 0, O absorbed O emitted П em 0.8 Times 10 to an exponent

This energy diagram shows the allowed energy levels of an electron in a certain atom or molecule: energy C Which is the ground state? B A Use this diagram to complete the table below. How many excited states are there? How many lines are in the absorption line spectrum? Which transition causes the absorption line at the shortest wavelength? Which transition causes the absorption line at the longest wavelength? (pick one) 0 0 0-0 0-0 ? 000 18 Ar

If photons have a frequency of 1.818x1015 s-1, what wavelength, in nm, does this correspond to?

An electron transitions from the n = (5.00x10^0) energy level to the n = (2.0000x10^0) energy. Calculate the energy, in Joules, associated with this energy transition. If the transition is exothermic be sure to include the appropriate sign. Use the equation: AE = - 2. 18 x 10-18J ( | | This is for administrative purposes only. Rydberg Constant = (2.180x10^-18) Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: х10 Answer
