▸ The reading
interpretive · artSeaborgium was the first element named for a person still living — Glenn Seaborg saw his own name enter the periodic table he had spent a career extending. Its oxychloride behaves exactly as group 6 predicts. The rarest honour in science, verified by the chemistry of a handful of atoms.

▸ Reactivity
Forms SgO₂Cl₂ — confirms group-6 chemistryGlenn Seaborg lived to see element 106 named in his honor — the first person to have an element named after them while still alive.
▸ Applications
- Probing relativistic effects in transition-metal chemistry
- Heavy-element synthesis
- (No commercial applications)
- (No practical bulk uses)
▸ Curiosity
The first element ever named after a living person — Glenn Seaborg approved seaborgium's name and was photographed pointing at his own symbol on the table.
