Surface Forms
Morphology
seaborgium = Seaborg (semi-transparent) = seaborg + ium
Formed regularly by adding the chemical element suffix '-ium' to the surname 'Seaborg'; the formation is regular but the meaning (a named element) depends on the proper name rather than compositional semantics.
Etymology
Seaborgium is named for American chemist Seaborg, who worked on many radioactive elements. The ending -ium is the usual ending for metal elements like sodium and calcium, so the name shows it is a chemical element and honors that scientist.
