Understanding Electron Capture and the Emission of X-rays

Click For Summary

Homework Help Overview

The discussion revolves around the process of electron capture in nuclear chemistry, specifically addressing the emission of X-rays following this process. The original poster expresses confusion about why an X-ray is emitted instead of a lower energy photon, highlighting a lack of resources on the topic in their chemistry class.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss the energy dynamics involved in electron capture and the nature of emitted radiation. Some question the accuracy of the original equation presented and clarify the distinction between X-rays and gamma rays. Others express a desire to understand the calculations related to photon energy during electron transitions.

Discussion Status

The conversation is ongoing, with various interpretations of the electron capture process being explored. Some participants have offered clarifications regarding the nature of emitted radiation, while others are seeking further understanding and calculations related to the topic.

Contextual Notes

There is mention of a lack of resources on nuclear chemistry in the original poster's textbook, which may be impacting their understanding. Additionally, some participants express uncertainty about the mathematical aspects of the discussion.

Homework Statement



This question actually comes from my chemistry class, but I believe it is more suited for this forum.

When the process of Electron Capture occurs, proton + e --> n, an x-ray is emitted. Why is that x-ray emitted and not a photon of lower energy.

Homework Equations



No idea

The Attempt at a Solution



This is an extra credit question, and I don't even know where to start. Our book doesn't even have a nuclear chemistry chapter. From some online sleuthing I can see that energy is released as electrons collapse, from the inner-most orbital out, but I do not understand why it would be an x-ray instead of a lower energy photon.

A point in the right direction would be appreciated. I might be able to understand some calculus if it's mathy, but I am not done with that class quite yet.

Thanks,
Mac
 
Physics news on Phys.org
in the process of electron capture the enregy released is very high. So a high energy photon is emitted. That is what x-ray is(a high energy photon).
 
Thank you. That's about the answer I submitted, but I was hoping I could show some of the calculations behind it.

For now though, I'll digress. I probably wouldn't understand most of it anyway at this juncture.
 
Ohk there are things i would like to say

1) the equation you have written is incorrect
p+e=n+nutrino is the right reaction.

2)X-ray is a not a part of above reaction. X-rays are not emitted generally in a nuclear reaction. Gamma rays emmited in nuclear reactions.

3)Yes X- rays are produced but after the K-capture. A vacancy is created in inner shell due to which an electron jumps from higher shell to the inner shell. The electron during jumping emits a photon to loose energy.

4) A simple question for you. As you have said you are good in maths. Can you calculate the energy of the photon if electron jumps from nth shell .

There is nothing like 'nuclear chemistry'. Every thing at nulear level is physics.

I think I'll pass for now, thanks. Maybe when I actually am good at maths. (if ever)

This wasnt the kind of reaction i was expecting. I am not challenging you. I am just trying a healthy discussion. And please excuse my poor english. I might sound rude even when i am potile.
