Difference between beta and electron particle

Click For Summary

Homework Help Overview

The discussion revolves around the relationship between beta particles and electrons, particularly in the context of radioactivity and nuclear emissions. Participants explore the nature of beta particles and their identification as electrons.

Discussion Character

  • Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • The original poster questions whether beta particles can be considered the same as electrons due to their shared charge, expressing uncertainty about the correctness of this assumption. Other participants clarify that beta-minus rays are indeed electrons and discuss the historical context of their identification.

Discussion Status

Participants are engaged in clarifying the definitions and characteristics of beta particles and electrons. Some guidance has been provided regarding their equivalence, but the original poster still expresses confusion, indicating an ongoing exploration of the topic.

Contextual Notes

The discussion includes historical references to the discovery of electrons and the classification of radiation types, which may influence participants' understanding of the terms involved.

hi..

we all know a electron and a beta patricle have charge -1e ..
now my question is.. when radioactivity takes place ..the nucleus emits beta particles sometimes...

now can we say that the electron is being emitted from the nucleus..since both beta and electron have the same charge..

i know tis is wrong...but don't know why...

does anyone have any clue ..??

Beta-(minus) rays are nothing but electrons. Beta+ rays, emitted in inverse beta decay, are positrons.
 
but in real how do we physically differentiate them..
 
We don't differentiate between beta-minus rays and electrons, if that's what you are asking. Electrons as a component of atom was discovered in 1897. Also, around 1896, the three kind of "rays" coming from radioactive decay was called alpha, beta and gamma rays. Afterwards, it was found that the beta rays were made up of high speed electrons.
 
ahh.. i get it hopefully...

tankx

chears !
