Question on the Bohr atomic model and energy

In summary, the Bohr atomic model is a simplified representation of an atom where electrons orbit around the nucleus in specific energy levels. The model also explains how electrons emit or absorb energy when transitioning between different energy levels. This theory was a breakthrough in understanding atomic structure and has been further developed by the quantum mechanical model.

Let's say there are three states ofor energym, E1, E2 and E3, and the electron is at E1, what happens if a photon has energy E > E2-E1 ?
Does it interact to the electron anD take it to E2 and the photon loose energy E2-E1 or it doesn't interact at ALL?
I mean, the electron can't have an energy greater than E2 and be in state E2

An electromagnetic wave can cause transitions between energy states of an atom even when it's not at exact resonance with the transition energy, but it will just as quickly cause a stimulated emission that brings the atom back to the original state. This can be shown by adding an oscillating time-dependent term in the Hamiltonian matrix of a 2-state system and solving the occupancies of the two energy states as a function of time.

in general the Frank-Hertz experiment showed the discrete nature of atomic transitions. the target atoms were invisible to electrons except for the energies shown below ie for cases like;

Does it interact to the electron anD take it to E2 and the photon loose energy E2-E1 or it doesn't interact at ALL?"the fact the line widths are not infinitely narrow is prolly worthy of a different thread.

1. What is the Bohr atomic model?

The Bohr atomic model was proposed by Niels Bohr in 1913 and it is a simplified representation of the structure of an atom. It states that electrons orbit around the nucleus in fixed energy levels, and that they can jump from one level to another by absorbing or emitting energy.

2. How does the Bohr atomic model explain energy levels?

The Bohr atomic model explains energy levels by stating that electrons can only exist in specific energy levels, and that they can transition between these levels by either gaining or losing energy. This helps to explain why certain elements emit light at specific wavelengths.

3. What is the significance of the Bohr atomic model?

The Bohr atomic model is significant because it was the first model to successfully explain the structure of an atom and its energy levels. It also laid the foundation for further understanding of atomic structure and the development of quantum mechanics.

4. How does the Bohr atomic model differ from the modern atomic model?

The Bohr atomic model differs from the modern atomic model in that it only describes the behavior of electrons in a hydrogen atom, whereas the modern atomic model takes into account the behavior of electrons in all atoms. The modern model also incorporates the concept of electron spin and the uncertainty principle.

5. Can the Bohr atomic model be applied to more complex atoms?

While the Bohr atomic model is a useful representation for simpler atoms like hydrogen, it cannot fully explain the behavior of more complex atoms. The modern atomic model, which incorporates quantum mechanics, is needed to fully understand the behavior of electrons in these atoms.
