A guide on how to add a reference to this article and fall in line with the general referencing style

Write a reference as you usually would in a template that is most appropriate for your reference: {{cite book}}, {{cite journal}}, {{cite web}}, {{cite report}}. Please use |first1=, |last1=, |first2=, |last2=, etc.; also, please add |displayauthors=3 if there are more than three authors. Please use initials instead of complete first names, the longer range notation for page numbers (1234–5678; 1234−1567; 123–145; 123–124), and the dmy date format ("1 January 1970"). Add author links if possible (via |authorlink=).

The following reference should look like this:

* {{cite book |last=Emsley |first=J. |authorlink=John Emsley |title=Nature's Building Blocks: An A-Z Guide to the Elements |year=2011 |publisher=Oxford University |isbn=978-0-19-850341-5 |page=236}} in the text near the claim.
