The Particle Model of emission and absorption is based on the idea that light is composed of discrete particles called photons, and these photons carry quantized energy. This model helps us understand how atoms and molecules interact with light by either emitting or absorbing photons during electronic transitions.

Emission and Absorption: Particle Model
The emission and absorption of radiation can be best described by the particle model. This model suggests that radiation is made up of particles, called photons, that carry energy and travel at the speed of light. Photons have no mass and are electrically neutral.
Emission:
Emission is the process by which an atom or molecule releases energy in the form of electromagnetic radiation. When an atom or molecule absorbs energy, its electrons move to higher energy levels. When these electrons return to their original energy levels, they release energy in the form of photons. The energy of the photons is directly related to the difference in energy between the two levels.
Absorption:
Absorption is the process by which an atom or molecule gains energy by absorbing electromagnetic radiation. When a photon interacts with an atom or molecule, it can be absorbed by exciting an electron to a higher energy level. The energy of the photon must match the difference in energy between the electron's initial and final energy levels.
Conclusion:
In conclusion, the emission and absorption of radiation are best described by the particle model. This model suggests that radiation is made up of particles, called photons, that carry energy and travel at the speed of light. When an atom or molecule absorbs energy, its electrons move to higher energy levels, and when they return to their original energy levels, they release energy in the form of photons. When a photon interacts with an atom or molecule, it can be absorbed by exciting an electron to a higher energy level.
