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?
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.
m
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.
