Nuclear equations and conservation of charge

Click For Summary

Discussion Overview

The discussion revolves around the representation of beta decay equations in nuclear physics, specifically addressing the conservation of charge in the notation used for the decay of carbon-14 to nitrogen-14. Participants explore whether the nitrogen product should be denoted with a positive charge or if the existing notation is sufficient.

Discussion Character

  • Debate/contested

Main Points Raised

  • Some participants question why beta decay equations are typically written without a positive charge on nitrogen, suggesting that it would be more accurate to denote nitrogen as N+.
  • Others argue that the notation used in textbooks is appropriate, as the charge of nitrogen is implicitly represented by its atomic number, which is 7.
  • A participant emphasizes that the equation pertains to the nucleus rather than the atom, indicating that the charge notation may not be necessary.
  • Another participant expresses agreement with the view that the positive charge is already accounted for in the atomic number of nitrogen.

Areas of Agreement / Disagreement

Participants express differing views on the necessity of indicating a positive charge for nitrogen in beta decay equations, with some supporting the traditional notation and others advocating for a more explicit representation.

Contextual Notes

The discussion does not resolve the question of whether the notation should include a positive charge, highlighting differing interpretations of charge conservation in nuclear equations.

Do you know why in most textbooks, like on http://www.lbl.gov/abc/Basic.html or http://books.google.com/books?id=xD0AwBQECasC&pg=PA196 beta decay equations are written like

[itex]^{14}_{6}C\rightarrow^{14}_{7}N+e^{-}+\overline{\nu}_{e}[/itex]

instead of

[itex]^{14}_{6}C\rightarrow^{14}_{7}N^{+}+e^{-}+\overline{\nu}_{e}[/itex]

Wouldn't the latter be more correct as regards conservation of charge ?

I usually see it written as

[itex]^{14}_{6}C\rightarrow^{14}_{7}N+^{ 0}_{-1}e+^{0}_{0}\overline{\nu}_{e}[/itex]
 
The equation is discussing the nucleus, not the atom. So no need to put a + in front of the N.
 
completely agree with Vanadium... the + is included in the 7 of Nitrogen
 
Thanks for all the replies.
