 |Portion           = 全圖片
 |Low_resolution    = The image is of a low size and resolution, sufficient to maintain the quality intended by the company, without being unnecessarily high resolution. At a lower size the compound would look just like an ordinary liquid. It does not limit the copyright owner's rights to market or sell the work in any way.
 |Purpose           = 用於展示鋂元素在首次被合成時的形態。
 |Replaceability    = 由於國家安全和法律限制問題，很難取得有關鋂的圖片。圖為該化合物首次被合成時的照片，因此不可取代。
 |other_information = 該圖片的使用符合維基百科的非自由內容方針，並符合美國版權法。
