MJM035 promethium exists but it's really not the same thing, electronium also exists but it's a random-music-generator and electrum (electronium's correct spelling) exists as well but is just a mix of gold and silver discovered by greek and used as money by them. So if you really want to choose a really-existing metal from this list, you have one more choice.
