Heavy metals - Wikipedia
Heavy metals are generally defined as metals with relatively high densities, atomic weights, or atomic nuers.The criteria used, and whether metalloids are included, vary depending on the author and context.  In metallurgy, for example, a heavy metal may be defined on the basis of density, whereas in physics the distinguishing criterion might be atomic nuer, while a chemist would likely
