In the Edit page of the elemental article, copy the Elem_Infobox template exactly as shown below and revise the example element name (elName) of Copper to the name of the 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.

The Infobox will be displayed on the right-hand side of the article's main page as shown 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:
