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.
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.
Nuclear isomers could be used to make a new kind of super-charged battery as they have energies of several mega electron volts (MeV) per atom, which could be released by shining light on them. One ...
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 ...
Isomers They have the same number of each type of atom. They can be part of the same or different homologous series, e.g. alkenes and cycloalkanes can be isomers.
Alternative approaches, such as using strong electric fields or lasers to separate out the isomers, have yet to bear fruit. Stern-Gerlach revisited The latest work, carried out by Gil Alexandrowicz ...
This article explains how NMR is used for differentiating between structural isomers with the chemical formula, C 4 H 8 O 2. Student Instructions. The three isomers discussed have unique carbon ...

Low-symmetry coordination cages enable sensitive recognition and selective enrichment ... - MSNThe 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 ...
Isomers are molecules with the same formula but different chemical structures. Classroom Ideas Can be used to recap on isomers or could lead into a classroom discussion on nature’s chemistry.
