Seconded.
Yeah… but I suppose a LOT of people would have to approve of it; maybe two or three at a time. But all within the span of about an hour or so.
Happiscrappium, goddammit.
It’s about time people RECOGNIZED.
Personally, I’m in love with fluiddruid’s suggestion. Genius!
Just thought of another two:
Millenium
or
Newmillenium
…ium?
manganesium
Any chance this new element is just too dense to recognize its own name?
Goatseum.
Wasabium
Fujium
Kamikazeum
Bonsaium
Karaokeum

Kenny: “MXCium…It’ll get us lots of chicks…”
Vic: “Right you are, Ken.”
“Rock dance, Paul! Do the rock dance!”
Anyway. In honor of Futurama, and because this heavy new element no doubt has a huge nucleus, I propose: jumbonium.
