Chapter 12 –Radioactivity
... • Most of the isotopes which occur naturally are stable. • A few naturally occurring isotopes and all of the man-made isotopes are unstable. • Unstable isotopes can become stable by releasing different types of particles. • This process is called radioactive decay and the elements which undergo this ...

Calculating the Atomic Radius of Polonium
... College of St. Benedict|St. Johnʹs University Three experimental facts are required to determine the atomic radius of a metallic element such as polonium: density, molar mass and crystal structure. The crystal structure of room temperature polonium is simple cubic, the only metallic element ...
