Decay chain
If it's stable, what's the meaning of "decay chain"? Jclerman 09:53, 3 February 2006 (UTC)

Origin
If it's the stars, how do we get it in our atmosphere? Jclerman 22:12, 17 February 2006 (UTC)

particle ?
Are you planning to make a particle of every one of the isotopes? Jclerman 21:06, 10 March 2006 (UTC)
 * What do you mean....? Kjaergaard 08:03, 11 March 2006 (UTC)
 * I don't know what do you mean by particle, but if you're consistent and categorize N-15 as a particle, then all isotopes (nuclides) would have also to be categorized as particles. Jclerman 10:24, 11 March 2006 (UTC)
 * I'm not particularly attached to the particle-stub template :-). But I guess it depends on from what perspective you have. If you thinking of it in a particle accelerator context (or some thing like it) then it might be valid categorization. But if you are doing NMR, then its definitely not a particle. Then you might even want to change it to chemistry-stub. Kjaergaard 18:16, 11 March 2006 (UTC)
 * No. Read the wiki entry for particle in the context of this article. N-15 and for that matter all other isotopes are composed of particles. If the person who dispenses stubs would read the definitions we would not waste time reverting stubs. I do not remember who put the particle stub, I know it was not you. BTW, perhaps you meant that an accelerator accelerates either particles or ions ? Jclerman 18:36, 11 March 2006 (UTC)

box again
Nowhere is an explanation of the meaning and how to derive such a table/box, despite comments posted for several isotopes. Not even the designer of the box has replied yet. Please explain as to make it useful. Jclerman 00:17, 7 May 2006 (UTC)

isotope-box templates

 * I posted several questions about them, months ago.
 * No comments.
 * A month later I commented out the boxes, put more questions.
 * Still no comments.
 * I asked the box designer or similar for info on how to generate such a template for a given isotope and the meaning of each one of the boxes.
 * The only reply I got was that the only known thing about the template was the template itself.
 * I'll appreciate it if you can replay and explain to me and all other users the questions summarized above and in the talk pages. Since nobody replied in the lapsed months, I assume not many users understand such boxes.
 * IMHO a couple of examples to be posted to a help page will help all users who don't understand these templates.

 * I'm sorry but I don't remember any of this. I originally created the isotope template back when I was just figuring out how templates worked. It was mostly an expirement, but I wanted it to be something actually useful instead of just a test. Every isotope has a decay chain, but nitrogen-15 is a stable nuclide, so it's at the end of it's decay chain. That's why it says "Decays to: Stable". It's analogous to succesion boxes that say "Succeeded by: Incumbent". What were the other questions? —Keenan Pepper 03:55, 7 May 2006 (UTC)
 * Some of the other questions have been mentioned at User talk:Ardric47 and User talk:Jclerman. Ardric47 04:28, 7 May 2006 (UTC)
