Roentgenium (AN = 111) was found by a team led by Sigurd Hofmann in 1994. In 2001, his discovery was deemed to have insufficient evidence, but subsequent confirmation in 2002 led to the formal recognition in 2003.
Roentgenium is a highly radioactive element that does not exist naturally and is only produced in laboratories. Due to its short half-life and high radioactivity, roentgenium is considered very dangerous. Handling even small amounts of roentgenium poses significant health risks.
It is supposed that the chemical properties of roentgenium are similar to the properties of silver.
