Froggy Jumps Bohr atomic modelVersion en ligne Prove that you are brave enough by answering this questions about the atomic model of Bohr! par Teresa Párraga Moreno 1 When did he introduce his constant in a formula explaining the light radiation by heated bodies? a 1901 b 1900 c 1898 2 In 1914, Bohr proposed his quantized shell model of the atom. a False b True c It is not said on the text. 3 What was Bohr's starting point? a The atom will be completely stable in the state with the smallest orbit. b The measure is close to the known size of atoms. c To realize that classical mechanics by itself could never explain the atom's stability. 4 What does classical theory say? a different amounts of light energy should be produced at all frequencies b comparable amounts of light energy should be produced at all frequencies. c comparable amounts of light energy should not be produced at all frequencies 5 What is quanta? a energy can only be emitted or absorbed in discrete amounts. b The latin word for how much. c The energy related to the frequency of the light 6 the radiation can occur only in quantum amounts of energy. a True. b False. c I do not really know. 7 Using Plank's constant, bohr discovered the next thing... a Bohr obtained an accurate formula for the energy levels of the hydrogen atom. b Bohr obtained an accurate formula for the energy levels of the energy. c Bohr obtained an atipical formula for the levels of the energy of the earth. 8 why electron orbits have fixed sizes and energies? a Quatization. b Electrons. c Fixed energy. 9 what happens if an electron jumps one orbit closer to the nucleus? a It must emit energy equal to the difference of the energies of the two orbits. b It must emit energy equal to the difference of the energies of the ten orbits. c It must emit energy equal to the add of the energies of the two orbits. 10 How they remedy the stability problem? a By modifying Rutherford model requiring that the energy move in orbits of same size and energy. b By modifying Planck's model requiring that the electrons move in orbits of fixed size and energy. c By modifying Rutherford model requiring that the electrons move in orbits of fixed size and energy.
