Write a text file with the missing chemical elements for the bilingual dictionary Spanish-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 Spanish, and B1 its transation into Catalan. For example for ''hidrógeno'' you would write
<e>       <p><l>hidrógeno<s n="n"/></l>               <r>hidrogen<s n="n"/></r></p></e>

The missing elements are already available in table format [4][5][6].
