Work
In chemical reactions, molecules composed of atoms meet and form new compounds. Electrons orbiting around the atoms’ nuclei play an important role here. In 1952, Kenichi Fukui developed a theory that showed that the properties of the orbits of electrons that are most weakly bonded to the atom are critically important in understanding chemical reactions. In later, more developed theories, Fukui and Roald Hoffmann proved independently of one another how the symmetrical properties of electron orbitals explain the course of chemical reactions.
Six prizes were awarded for achievements that have conferred the greatest benefit to humankind. The 10 laureates' work and discoveries range from optogenetics to efforts to promote peace and international law.
