Charge in the electrons and protons

Click For Summary
SUMMARY

The discussion centers on the fundamental properties of electrons and protons, specifically their charges, which are negative and positive, respectively. This was established by J.J. Thomson through experiments using a discharge tube, where cathode rays were observed moving from the cathode to the anode, confirming the negative charge of electrons. The conversation also touches on the concept of charge oppositeness, reinforcing the established understanding of atomic structure.

PREREQUISITES
  • Understanding of basic atomic structure
  • Familiarity with J.J. Thomson's experiments
  • Knowledge of electric charge concepts
  • Basic principles of cathode ray tubes
NEXT STEPS
  • Research J.J. Thomson's discharge tube experiments in detail
  • Explore the concept of electric charge and its implications in atomic theory
  • Learn about the historical development of atomic models
  • Investigate other experiments that demonstrate charge properties, such as Millikan's oil drop experiment
USEFUL FOR

Students studying physics, educators teaching atomic theory, and anyone interested in the foundational concepts of electricity and atomic structure.

dear reader,
the electrons are negative and protons are positive was proved by jj thompson. he proved it using the discharge tube. the cathode rays which started from the cathode(-) to the anode(+) was said to be negative because of its attraction to the anode. is there any other experiment or theory that proves that electrons are negative and protons are positive?:smile:. i am only in 9th std, so please don't be angry with me for this question.

thanks

thanks mmwave. i fell that electrons can also be positive provided that the protons are positive. i get it clear now , they are just opposite charges.
:smile:
