I'm bothered by the Rd symbol of Radon on the page, it's should be Rn. It makes me double-check if there's actually an element that's not Radium (Ra), not Radon (Rn), but also starts with an R and has a d in its name.
Noticed this too, it's been since fixed :)
Rhodium, but that's Rh.
Neat, one more element to the "Rd" element group.
