Quiz zum Vortrag
Before the Bohr model, how were positive charges considered to be distributed in an atom?
- Spread out throughout the atom
- Concentrated in the center
- Orbiting the center
- Forming concentric rings
- Spread uniformly in a spherical shell
What are the possible energy levels n of an electron in an atom? And what is the maximum number of electrons that can occupy each level?
- n = 1, 2, 3, ..., Max. number of electrons at each level : 2n²
- n = 0, 1, 2, ..., Max. number of electrons at each level : n²
- n = -2, -1, 0, 1, 2, ..., Max. number of electrons at each level : 2n²
- n = 1/2, 2/2, 3/2, ..., Max. number of electrons at each level : n²
- n = 0, 1/2, 2/2, 3/2, ..., Max. number of electrons at each level : 2n²
How many electrons can occupy the n = 3 energy level?
- 18
- 16
- 20
- 14
- 10
How is a photon emitted from an excited atom? And what is the relation between the emitted photon energy E and its frequency f?
- When electrons in an atom are dropped from an excited state to a lower energy state the energy difference is released in the form of the emission of a photon, E = hf
- By raising electrons to higher energy levels, E = hf
- By swapping two electrons in adjacent energy levels, E = E₀ f/f₀
- By losing an electron from the atom, E = E₀ f/f₀
- The excited atom collides with other atoms and releases its kinetic energy in the form of an emitted photon, E = hf
