4. When a hydrogen atom is bombarded, the atom may be raised into a higher energy state. As the excited electron falls back to the lower energy levels, light is emitted. What are the three longest-wavelength spectral lines emitted by the hydrogen atom as it returns to the n = 1 state from higher energy states? Give your answers to three significant figures. The lowest possible state, n = 1, corresponds to the electron in its smallest possible orbit; it...
A hydrogen atom is excited to a 3? electronic state. Two photons are emitted, one after the other. For ten points each what are their (positive) energies, in eV (two digit accuracy)
For the hydrogen atom, its energy at ground state is 13.6 eV, at first excited state is 3.4 eV at second excited state is 1.5 eV and at the third excited state is 0.85 eV. i) Give the energy value for the first two states in Joule (J). [1eV =1.6 x 10-19 J] (2 marks) ii) With the aid of schematic diagram, determine the energy of emitted photon when the atom jumps from the first and third excited states to...

(20 pts) A hydrogen atom is excited to a 3d electronic state. Two photons are emitted, one after the other. For ten points each, what are their (positive) energies, in eV (two digit accuracy is fine)? Photon energy/eV Photon energy/eV
Electrons in an unknown atom(not hydrogen) are excited from the ground state to the n=3 energy level. As these electrons make quantum jumps back to the ground state, photons of three different energies are emitted. The most energetic photon has an associated wavelength of 62.2 nm and the least energetic photon has an associated wavelength of 207 nm. What is the associated wavelength of the other type pf photon? The answer is 3-1 (20 eV), 3-2 (6 eV) and 2-1...

Question 1: Which photon energies will excite the Hydrogen atom when its electron is in the ground state (Hint: there are 5 named on the simulator, though there are more Question 2: Starting from the ground state, press the L, button twice in succession (that is, press it a second time before the electron decays). What happens to the electron? Question Complete the energy mange values for the excited state...
