Talk:Hydrogen spectral series

message: As the separate pages contain little information that isn't duplicated here, I will merge them into this article, retaining all additional information, unless there are any objections? OrangeDog (talk) 19:26, 24 December 2008 (UTC)
replies: text: This would also involve changing the existing pages to redirect, and removing :Template:Hydrogen spectral series-footer. OrangeDog (talk) 20:10, 27 December 2008 (UTC)
replies: text: I have performed a partial merger, leaving Lyman and Balmer with their separate pages, as they are significantly more developed. OrangeDog (talk) 16:09, 29 December 2008 (UTC)
replies: text:  No. What you've done is okay, leaving the others as summary-main redirects. But more would be working backwards. Wikipedia grows by means of WP:SS. You don't help Wikipedia grow by finding places to merge stubs, just because they're stubs. Separate articles are places which invite people to find and add more specific information. Leave them alone to grow, unless they are merely renaming. SBHarris 22:29, 19 January 2009 (UTC)
replies: text: Should the remaining series become notable in their own right I'm sure WP:SS will take affect as more info can be added. Until then, this seems the optimal solution. –OrangeDog (talk • edits) 02:54, 20 January 2009 (UTC)
thread_title:  Merge proposal 

message: As a general note you might want to read WP:LEAD and WP:BCLASS (if you haven't already) as they can give general hints as to improve articles in general. More specific:
*The lead should be a reflection of the content of the article. Right now the lead contains a lot of information that does not appear anywhere else in the article. There should probably be section in the article discussing the relation between the Rydberg formula and the Hydrogen series. Its contents should be summarized in the lead.
*How standard is the usage of n' and n as variables in the Rydberg formula? Not everyone will be familiar with using primed letters as variables, so if we can avoid this we probably should. n and m would work fine. Or n and k.
*:Every source listed (and others I've seen) use primed variables. OrangeDog (talk • edits) 13:00, 10 July 2009 (UTC)

thread_title:  Some suggestions 

message: I bring up this discussion because I'm curious as to the reasons for what I see as an error. The emission line wavelength of Pa-alpha is 1875.64 (observed) or 1874.607 (using the value of the Rydberg Constant on the page). OrangeDog insists that the page should display 1870 nm, as this is three significant figures, using the formula on the page. However, I think this is misleading, as the number "1870" as presented indicates that there are four significant figures. (Despite the easy to miss note at the top of the page declaring all the wavelengths presented are only three significant figures.) If we really only intend to present three significant figures, then the wavelength should be presented as "1.87*10^3 nm". Perhaps someone can enlighten me in the view of presenting this as "1870 nm", particularly when the Rydberg Constant is presented with many more significant figures? I'm sure this issue must affect the other lines on the page.  Uayebforever (talk) 00:32, 16 June 2011 (UTC)
replies: text: Now you point it out, it probably should be written as 1.87, but I'd go for μm rather than the exponent. In order to avoid problems reconciling various sources giving empirical values to various precisions, I felt it would be better to peg to a single source and give the calculated values. The choice of 3sf means it agrees with most other sources (apart from this one value) and other readers/editors don't get confused as to why the numbers don't match, or the equation is "wrong".

thread_title:  Wavelengths of lines 

message: It would be good to add a phonetic pronunciation of Pfund given that this is used in intro chem textbooks and online students may come here to figure that out. I presume that it is pronounced as "Fund" (e.g.: https://www.youtube.com/watch?v=FTKIK_JEFzg ), but could not verify that from another source.  — Preceding unsigned comment added by 67.246.34.112 (talk) 17:53, 18 November 2015 (UTC)
thread_title:  Pronounciation of Pfund 

message: The section on the Rydberg formula says "where z is the atomic number, i.e. the number of protons in the atomic nucleus of this element"  z is not in the formula here nor any place in section. Perhaps this is mistake from coping this section from elsewhere? Love! this article though, its great easy to read info. Tpsawyer (talk) 21:38, 20 October 2016 (UTC)
replies: text: Hey, I have tried to clarify it. Is it fine now? :) extra999 (talk) 08:36, 24 October 2016 (UTC)
thread_title:  Atomic number Z 

message: The spectral series of hydrogen, on a logarithmic scale.
The emission spectrum of atomic hydrogen has been divided into a number of spectral series, with wavelengths given by the Rydberg formula. These observed spectral lines are due to the electron making transitions between two energy levels in an atom. The classification of the series by the Rydberg formula was important in the development of quantum mechanics. The spectral series are important in astronomical spectroscopy for detecting the presence of hydrogen and calculating red shifts.
