Electron centripetal acceleration

Click For Summary
SUMMARY

Electrons do not exhibit centripetal acceleration while occupying an orbital, contrary to classical physics expectations. The notion that electrons radiate electromagnetic waves while revolving around a nucleus has been debunked due to significant theoretical issues. Instead, electrons maintain angular momentum without the classical mechanics framework, leading to ongoing scientific inquiry into their behavior.

PREREQUISITES
  • Quantum mechanics fundamentals
  • Understanding of atomic orbitals
  • Familiarity with angular momentum in quantum systems
  • Knowledge of electromagnetic radiation principles
NEXT STEPS
  • Research quantum mechanics and the behavior of subatomic particles
  • Explore the concept of angular momentum in quantum physics
  • Study the implications of electromagnetic radiation in particle physics
  • Investigate the historical context of classical vs. quantum mechanics
USEFUL FOR

Physicists, students of quantum mechanics, and anyone interested in the behavior of electrons in atomic structures.

hi experts
electrons certainly have centripetal acceleration - and we learned that accelerated particles do emit EM waves - than does electron radiate while revolving around nucleus?

Welcome to PhysicsForums, wasi-uz-zaman!

Electrons do not behave in the manner you describe, and they do not radiate while occupying an orbital. The idea that they did was recognized long ago as leading to serious theoretical problems.
 
The electron has no centripetal acceleration. It obeys no law from classical physics.
 
OK then why electron have angular momentum

Scientists do not know yet.

As far as they know, "It just does."
