grumpyborg

Seaborgium with a bad attitude.

Radioactive state makes Seaborgium toxic to organisms and so has no biological role. Also, because the half-life is very short, it doesn't exist long enough for any commercial use. Most radioactive elements are used within the laboratory for experimentation.

That grumpyborg just pissed off the entire audience.
