 |Portion           = Full image.
 |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 metal piece would look just like an ordinary metal. It does not limit the copyright owner's rights to market or sell the work in any way.
 |Purpose           = The image is used to illustrate and identify the radioactive element in its pure form.
 |Replaceability    = A free replacement image could not be created due to national security and safety restrictions against public handling or viewing the element. This image is one of the very few, or quite possibly the only one published on the pure element.
 |other_information = Use of image in the following articles complies with Wikipedia [[Wikipedia:Non-free content|non-free content policy]] and fair use under [[fair use|United States copyright law]] as described above.
