Roentgenium

Rg

INTRODUCTION

Roentgenium is an extremely rare, unstable chemical element. The large number of particles in the nucleus makes the atom unstable and causes the atom to split apart into smaller components soon after it is created.

It was named roentgenium in honour of German physicist Wilhelm Conrad Roentgen, the discoverer of X rays. It was first discovered in 1994 by scientists at the Heavy-Ion Research Laboratory in Darmstadt, Germany.
