The article focuses on a study by professor Thomas Graedel and colleagues which examined the criticality of metals on the periodic table. Topics covered include the metals traditionally used in manufacturing, the factors affecting criticality such as geological abundance and the supply limits for metals...

The most reactive of all metals, it is pyrophoric and reacts with water even at −116 °C (−177 °F). It is the least electronegative element, with a value of 0.79 on the Pauling scale. It has only one stable isotope, caesium-133. Caesium is mined mostly from pollucite, while ...

Actinium gave the name to the actinide series, a group of 15 similar elements between actinium and lawrencium in the periodic table. Together with polonium, radium, and radon, actinium was one of the first non-primordial radioactive elements to be isolated. A soft, silvery-white radioactive ...
