Group 11 elements

Group 11 elements include copper, silver and gold. These elements are certainly known to almost everyone.

Not so well known is the unstable Roentgenium, which researchers artificially produced a few years ago. It was named after the physicist Wilhelm Conrad Röngen, who discovered the X-rays named after him in 1895. For this he received the first Nobel Prize in Physics in 1901. X-rays are still indispensable for medical diagnostics today.
