Roentgenium (element)

Roentgenium is a very rare and highly unstable chemical element with the symbol Rg and atomic number 111. It was named after Wilhelm Röntgen, who discovered X-rays. Found deep within the periodic table, it belongs to the group of transition metals. Because its atoms are so unstable, Roentgenium exists only for a fraction of a second in laboratory conditions. Scientists synthesize it by nuclear reactions, but it has no significant commercial uses due to its brief existence and radioactivity. Its primary importance lies in scientific research, helping us understand nuclear physics and the behavior of heavy elements.
