Isomers like technetium are safe for medical use because they emit only a single, harmless photon at a time and nothing else as they decay. Isomers are also important in astronomy and astrophysics.

The discovery of buckminsterfullerene (C 60) marks a milestone in the study of three-dimensional carbon materials.However, as the number of isomers increases exponentially in higher fullerenes (C ...

Nuclear isomers are rare versions of elements with properties that mystified physicists when first discovered. Isomers are now used in medicine and astronomy, and researchers are set to discover ...

Higher; Systematic carbon chemistry Isomers. Carbon chemistry involves many different families of compounds and the reactions needed to interchange them. Understanding the properties of different ...

The stability of an atomic nucleus is determined by the outcome of a tug-of-war between the attractive strong nuclear force and the repulsive electrostatic force between the protons in the nucleus.
