This has an obvious answer, in a covalent bond, each atom contributes an electron & in turn shares the other electron contributed by other atom. Compare this situation with Ionic bond where electrns get completely transferred & the atoms get ionized (charged). So it concludes that atoms are neutral originally (Obviously).\nSo in a homolytic fission when electrons contributed by atoms are RETURNED back to them, why should they get charged ? They in a sense return to their original NEUTRAL atomic state i.e. a free & reactive radical .\n\nHAPPY NEW YEAR !\n:-)
In homolytic fission a covalent bond breaks and each atom gets an electron from the bonded pair?
