Elements and compounds are mutually exclusive categories, and no examples are possible. The questioner may be referring to molecular elements, which are molecules containing more than one atom of a single element. Examples of these are hydrogen, oxygen, nitrogen, and all the halogen elements (column 17 of a wide form periodic table).
