Bohr's Hydrogen Model: Does Electron Absorb All Energy?

In summary, the conversation discussed the absorption of light by an electron and its corresponding increase in energy. It was mentioned that the Bohr model of the hydrogen atom, while historically significant, is not entirely accurate and has been replaced by modern understandings of quantum mechanics.

Provided the electron absorbs light of frequency ##f##, if the electron's initial energy was ##E##, is the energy now ##E + hf##? In other words, does it absorb all of that energy?

Yes.It absorbs all energy

Do remember, however, that Bohr's model of the hydrogen atom is mostly of historical interest - it pointed people in the right direction a century ago, but it is not what's really going on. So if you find contradictions and problems as you think through the implications of RyanH42's (generally correct) answer... That's to be expected, and indeed these difficulties are part of what motivated the physicists of the era to keep on looking, and how we eventually came to first Schrodinger's equation and then the modern understanding of both quantum mechanics and the hydrogen atom.

I don't know QM.So as Nugatory said I considered Bohr Atom Model.
 

1. What is Bohr's Hydrogen Model?

Bohr's Hydrogen Model is a scientific model proposed by Danish physicist Niels Bohr in 1913 to explain the structure of the hydrogen atom. It states that electrons orbit the nucleus in specific energy levels, and can move between these levels by absorbing or emitting energy in the form of photons.

2. How does this model explain electron absorption of energy?

In Bohr's model, electrons can absorb energy by moving from a lower energy level to a higher one. This energy is then stored in the electron's orbit, allowing it to stay in the higher energy level until it emits the energy and returns to its original level.

3. Does the electron absorb all energy when it moves to a higher energy level?

No, the electron does not absorb all energy when it moves to a higher energy level. According to Bohr's model, the electron can only absorb a specific amount of energy to move to a higher energy level, and the energy absorbed corresponds to the difference in energy between the two levels.

4. Can an electron absorb any amount of energy?

No, an electron cannot absorb any amount of energy. It can only absorb a specific amount of energy to move to a higher energy level, as determined by the energy difference between the two levels in Bohr's model.

5. How does Bohr's model explain the emission of light from atoms?

Bohr's model explains the emission of light from atoms by stating that when an electron moves from a higher energy level to a lower one, it emits energy in the form of a photon. This energy corresponds to the difference in energy between the two levels, and the wavelength of the emitted photon determines the color of the light.
