Write a text file with the missing chemical elements for the bilingual dictionary English-Catalan with the requested file format [1][2][3].

File format

<e>       <p><l>A1<s n="n"/></l>               <r>B1<s n="n"/></r></p></e>
<e>       <p><l>A2<s n="n"/></l>               <r>B2<s n="n"/></r></p></e>
<e>       <p><l>A3<s n="n"/></l>               <r>B2<s n="n"/></r></p></e>
...
....

Where A1 is the name of a missing element in English, and B1 its translation into Catalan. For example for ''sulfur'' you would write
<e>       <p><l>sulfur<s n="n"/></l>               <r>sofre<s n="n"/></r></p></e>
 
The missing elements are already available in table format [4][5].
