In [[CZ:Chemistry style guide#Chem infobox and Elem Infobox|this section]] of the [[CZ:Chemistry style guide]] article, the use of the [[Template:Elem Infobox]] is advocated for use in the main article page of articles devoted to any of the [[chemical elements]] listed in the [[Periodic table of elements]]. However, neither the chemistry style guide nor the template articles provide any simple, understandable instructions on how to install the Elem Infobox in an article.
Some of the articles about specific chemical elements already have the Elem Infobox template installed in them. However, some have installed the [[Template:Basic elemental info]] which is similar but much less desirable because:
*In addition to the infobox, it automatically generates the first three paragraphs of the article's introductory section (also called the "lede") and they are not editable (i.e., not visible on the article's Edit page).
*It automatically creates hyperlink <nowiki><ref></ref></nowiki> references to a website page of the Los Alamos National Laboratory which result in a "Not found" error message. The hyperlink references are also not visible on the article's Edit page and therefore cannot be simply removed.
As stated in the CZ:Chemistry style guide, the Elem Infobox is preferable. It is simpler and it does not automatically generate any non-editable lede paragraphs or any hyperlinks. The author of the article is free to write the lede and to provide any references as he/she desires.
==Installing the Elem Infobox==
This article provides an explanation how to install the Elem Infobox at the top right-hand position in the lede of articles devoted to any of the chemical elements. 
In the Edit page of any article about a chemical element, copy the Elem Infobox template exactly as shown below and revise the example element name (elName) of Copper to the name of the specific element desired. Don't worry about entering anything else, if you don't know what to enter. Someone knowledgeable will eventually fill in other information or you can ask a Chemistry editor for help.
<pre>
{{Elem_Infobox
|background1=f2f2f2
|align=right
|elementColor=f5f5f5
|elName=Copper
|eltrnCfg=
|elgroup=
|elperiod=
|elblock=
|no1=
|no2=
|no3=
|no4=
|properties=
|compounds=
|uses=
|hazard=
}}</pre>
The Infobox will be displayed on the right-hand side of the article's main page as shown to the right and just below, once you have copied the above template into the article's Edit page, revised the element name to the name desired (Gold, for example), and then saved the Edit page.
{{Elem_Infobox
|background1=f2f2f2
|align=right
|elementColor=f5f5f5
|elName=Gold
|eltrnCfg=
|elgroup=
|elperiod=
|elblock=
|no1=
|no2=
|no3=
|no4=
|properties=
|compounds=
|uses=
|hazard=
}}
The large, dark blue letters '''[[Au]]''' are the [[chemical symbol]] of the element. The number 196.96655 in the upper left is the [[Atomic weight]] and the number 79 is the [[Atomic number]] of that element.
The bottom part of the infobox contains a miniature reproduction of the [[Periodic table of elements]] and the different colors represent the different ''groups'' of elements such as Non-metals (including Noble Gases), Main Group Metals, Transition Metals and Metalloids.
The location of the element within the miniature periodic table is indicated by coloring it black and the words "Transition metal" (just above the miniature table and to the left) names the group to which the element Gold belongs.
See the [[Phosphorus]], [[Nitrogen]] and [[Gold]] articles as examples of how the Elem Infobox looks when it is filled in with additional information.
<br/><br/>
==Suggested optional first paragraph for the lede==
The following two-sentence paragraph is a suggested and optional, optional first paragraph for the introductory part of the article (i.e., the lede):
<blockquote>
<font color=green>Gold</font> is a [[Chemical elements|chemical element]] having the [[chemical symbol]] <font color=green>Au</font>. Its [[atomic number]] (the number of [[proton]]s) is <font color=green>79</font> and its  [[Atomic mass#Standard atomic weights of the elements|standard atomic weight]] is <font color=green>196.96655</font>. It is typically found as a [[solid]] in its elemental form.
</blockquote>
All of the items colored green in the above optional lede should be changed as needed for the specific desired element. Also, look at the edit page of this article to see how to correctly create the blue wiki links in the optional lede.
Following the lede and the infobox, the article text may then be expanded and reformatted in whatever way you wish.
==Replacing [[Template:Basic elemental info|Basic elemental info]] with [[Template:Elem Infobox|Elem Infobox]]==
If you want to remove the [[Template:Basic elemental info]] (from an existing article about an element) so that you can replace it with the [[Template:Elem Infobox]], simply delete the '''<nowiki>{{Basic elemental info}}</nowiki>''' template from the top of the main article's Edit page. You can then replace it with Elem Infobox template as instructed above.
If the existing article's main page still retains a hyperlink reference to a page on the website of the Los Alamos National Laboratory (LANL), then:
*Go to the table of properties in the "Properties" subpage of the existing article.
*Click on the numeric value of the Melting Point. That will take you to another subpage that has the melting point numeric value as well as the hyperlink reference. Go to the Edit box of that subpage and delete the <nowiki><ref>XXXXX</ref></nowiki> (where XXXXX is the hyperlink address of the reference). Then preview and save that subpage.
*Go back to the existing article's main page and reload (or refresh) the page. The uneditable hyperlink reference will be gone.
