The Periodic Table and the Actinides

Most people know that uranium is radioactive, but few would think of taking a Geiger Counter with them when antique-hunting. A hundred years ago, uranium oxide was widely used in making decorative glass objects. Their characteristic greenish-yellow colour gave them the name of ‘Vaseline glass’, though their radioactivity means that uranium is not used in glass-making these days. Uranium is also used in making the shells fired by Army tanks, as it is extremely dense and also tends to ignite on impact.
