Wikipedia:WikiProject Elements

From Wikipedia, the free encyclopedia
This is an old revision of this page, as edited by Mav (talk | contribs) at 09:23, 23 December 2002 (Silver is done). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

This WikiProject is aimed at facilitating the conversion of the current periodic table element articles to the agreed upon format discussed in Talk:WikiProject Elements.
For an example of what the new format will look like, please see Beryllium. For a clean copy of the template being used please see the bottom of this page.

Other languages

Somebody has already translated one of these tables into Dutch at nl.wikipedia.com/wiki/Boor. I encourage this type of translation and when all the English versions of the element articles are done I plan on doing a find and replace on all of the tables (in one file) in order to quickly translate each table. Of course, at least one good translated table is needed before this is done for any particular language. Others are more than welcome to do this work before the English versions of the element articles are done, but be forwarned, plans are already being made for several significant changes to the tables and the template is evolving all the time.

Next Phase

The most significant thing being planned is the addition of a locator map image and a relative atomic size diagram similar to the one found at environmentalchemistry.com - Tin. No part of the images will be in English so they will be usable for every language. All the current tables have been modified to allow for easy nav/map upgrade later. --mav

Here is the full-sized master image template. An example of a smaller version in action can be found at Lithium.

Temporary page header template

''This is a temporary page created for the sole purpose of converting the current [[_]] article over to the new format agreed upon in [[Wikipedia talk:WikiProject Elements/Archive 1]]. When this process is complete the content in this page will be moved to the main article and any relevant edits made to that version will be incorporated into this version (this page will then be deleted from the database).

Color scheme
Table headings will all have fill colors that match the fill colors used for that elements chemical series in the periodic table.

Rationale for colors of the New Table
Alkali metals #FF6666Very reactive and therefore dangerous = red
Alkaline earths #FFDEADnice earthy color = easy to remember.
Lanthanides #ffbfffSuggestions? The current color was chosen arbitrarily.
Actinides #d0d0ffSuggestions? The current color was chosen arbitrarily.
Transition metals #ffc0c0Another shade of gray (or even silver) would work here. But that would make to table a bit drap and the colors of the metals and transitions metals too similar. I am up for suggestions. Does any other common property of the transition metals have a color associated?
Metals #cccccctrue metals are closest in color to gray
Semimetals #cccc99 Intermediate color between above and below
Nonmetals #a0ffa0Elements most essential to life. Most life on Earth (measured by biomass) is photosynthetic and chlorophyll is green
Halogens #ffff99Fluorine gas is yellowish as are many precipitates of halogens
Noble gases #c0ffffNon-reacative for practical purposes. Light-blue is soft and soothing (it is also the opposite of red)

MAIN TEMPLATE

To make the links at the bottom of this template active the underscore within the links needs to be replaced. For Los Alamos National Lab replace the URL _ with the atomic number. For the USGS page replace the URL _ with the element's name (lowercased). For the other two links replace the _ with the element's symbol.

This is a temporary page created for the sole purpose of converting the current [[_]] article over to the new format agreed upon in Wikipedia talk:WikiProject Elements/Archive 1. When this process is complete the content in this page will be moved to the main article and any relevant edits made to that version will be incorporated into this version (this page will then be deleted from the database). For an example of what this article will look like when complete, please visit Beryllium, for a clean copy of the template used here please visit WikiProject Elements.

Occurrence

Compounds

Isotopes

Naturally occurring _ is composed of _ stable isotopes. _ radioisotopes have been characterized with the most {abundant and/or stable} being _-_ with a half-life of _, _-_ with a half-life of _, and _-_ with a half-life of _. All of the remaining radioactive isotopes have half-lifes that are less than _ and the majority of these have half lifes that are less than _. This element also has numerous meta states with the most stable being _m-_ (t½ _), _m-_ (t½ _) and _m-_ (t½ _).

The isotopes of _ range in atomic weight from _ amu (_-_) to _ amu (_-_). The primary decay mode before the most abundant stable isotope, _-_, is [[{name of decy mode}]] and the primary mode after is [[{name of decy mode}]]. The primary decay product before _-_ is [[{element name}]] (element _) and the primary product after is [[{element name}]] (element _).

Notes

  1. Even though this text was paid for by CA State and US Federal tax dollars, it may be covered by a semi-proprietary license held by the UC Regents and therefore needs to be slightly rewritten so that it passes the Google test (specifically they don't allow for commercial redistribution without permission which is not compatible with our license). The UC Regents claims copyright on most texts at LANL and the 3 emails I sent to them requesting the status of the perio text were never answered. In addition, the LANL periodic table hasn't been touched since 1997 but it has won several awards. --mav
  2. This is public domain material and can be copied verbatim but it isn't available for every element. The text may also be under a different name. They sometimes combine entries, such as iron and steel. If nothing comes up, then look for the element at http://minerals.usgs.gov/minerals/pubs/commodity/ .
  3. These databases are covered by more or less public domain licenses. The main thing that is asked for is some attribution (which isn't mandatory but would be nice to have on talk pages). This material is useful when creating the definition/introduction paragraphs.
  4. This is public domain isotope info and can be copied verbatim but it is very technical and usually only the first paragraph or two are useable at all (the focus of the USGS perio table is hydrology and we needn't fill our perio table with material that is that specialized). Not all elements are included in this source. Several months ago I ported over all the elements that they then had. Since then, however, they seem to have either added more elements to their database or I somehow missed some. --mav
