Aprašymas
More than 100 years ago, scientistsdiscovered that many elements com-monly found on earth occur in differ-ent atomic configurations. These vary-ing configurations, called isotopes, were found to have identical electroni-cally charged particles and identicalchemical properties, but differentatomic weights and physical properties
