Only thorium and uranium are naturally occurring actinides with significant abundance. Superconductor lasers shed heat much easier than glass lasers, said John Badding, a materials chemist at Penn State University. This shows that the classification of the elements on the basis of their atomic masses is not correct. Clinical chemists measure a variety of substances, ranging from simple elements such as sodium and potassium to complex molecules such as proteins and enzymes, in blood, urine, and other body fluids. All the gaseous elements are definitely nonmetals, so hydrogen is sort of on the wrong side.
