Phosphore hypervalent
WebHypervalent molecules have a central atom that has more electrons than needed for a noble gas configuration. Odd-electron Molecules. We call molecules that contain an odd number of electrons free radicals. Nitric oxide, NO, is an example of an odd-electron molecule; it is produced in internal combustion engines when oxygen and nitrogen react at ...
