The energy levels for a Bohr atom are shown below. Use this diagram to solve problems 7 and 8.
0 eV
-2.5 eV
-4.0 eV
-7.0 eV
-12.5 eV
7. What amount of energy is needed for an electron to jump from n = 1 to n = 4?
8. What is the wavelength of the photon needed to make this happen? Is it emission or absorption?
What is an emission spectrum? Use the Bohr model to explain why the emission spectrum of the hydrogen atom consists of distinct lines at specific wavelengths.
Be sure to answer all parts.
Consider the following energy levels of a hypothetical atom:
E4-2.51 × 10-19 J
E3-5.01 10-19 J
E2 -1.25 x 10-18 J
E₁-1.85 × 10-18 J
(a) What is the wavelength of the photon needed to excite an electron from E₁ to E4?
x 10
(b) What is the energy (in joules) a photon must have in order to excite an electron from E₂ to E3?
x 10
m
x 10
J
(c) When an electron drops from the E3 level to the E₁ level, the atom is said to undergo emission.
Calculate the wavelength of the photon emitted in this process.
