SUMMARY

The discussion centers on the misconception that light is absorbed by the nucleus of an atom rather than by its electrons. Participants clarify that when light is absorbed, it is the electrons that gain energy and transition to higher energy levels, not the nucleus. The attractive force between the nucleus and electrons influences their orbits but does not dictate energy absorption. Quantum mechanical properties define the energy levels of electrons, which must match the energy of incoming photons for absorption to occur.

PREREQUISITES
  • Understanding of atomic structure and electron configurations
  • Familiarity with quantum mechanics principles
  • Knowledge of photon energy and its interaction with matter
  • Basic concepts of energy levels and electron transitions
NEXT STEPS
  • Research "Quantum Mechanics and Electron Energy Levels" for deeper insights
  • Study "Photon Absorption and Emission in Atoms" to understand energy transfer
  • Explore "Atomic Orbitals and Their Shapes" to grasp electron configurations
  • Learn about "The Role of the Nucleus in Atomic Structure" for a comprehensive view
USEFUL FOR

Students of physics, educators in atomic theory, and anyone interested in the fundamental interactions between light and matter will benefit from this discussion.

Another way to think ...

Dear reader,
Now what i am writing suerly would look different from the reason give by physicists about black body absorption of light.
Before i begin i would like to make certain things clear.
1) let's asume when more energy is given, the speed of electrons does not increase. Only they jump to a higher level.
2) the more further we go from the nucleus, the attractive force between the nucleus and electron get weeker.
3) the attractive force is completely dependent on the nucleus of an atom.
4)when light is absorbed by an atom the electrons jump to a higher level and when light is lost by an atom the electrons fall to a lower level.

now if am wrong any where till now please let me know, don't read the continuation.

i believe that light is absorbed by the nucleus of an atom and not by the electrons.

here are the reasons why i believe so,
i feel that the nucleus on absorption of photons lose energy which enable the electrons to jump to higher level.
as mentioned above the nucleus is what determaines the orbits of an atom.

-benzun,
if i am wrong please let me know.
 
Physics news on Phys.org
That would suggest that ALL the electrons go up an energy level when the atom is energised. But that, as far as I know, is not supported by experiments.
 


Dear benzun,

Thank you for sharing your thoughts on the absorption of light by the nucleus of an atom. While it is true that the nucleus plays a crucial role in determining the orbits of electrons, it is actually the electrons themselves that absorb the energy from the photons of light.

When a photon of light is absorbed by an atom, it transfers its energy to an electron, causing it to jump to a higher energy level. This is because electrons exist in specific energy levels, and can only occupy those levels. The energy of the absorbed photon must match the energy difference between the current and higher energy level for the electron to make the jump.

Additionally, the attractive force between the nucleus and the electrons does not determine their energy levels. The energy levels are determined by the quantum mechanical properties of the atom, such as the shape and size of the electron orbitals.

I hope this helps clarify the role of the nucleus and electrons in the absorption of light. Keep exploring and questioning the world around us!
