This is because chemical reactions generally involve electrons rather than protons or neutrons. Physical Properties: The physical properties of isotopes differ because the atomic masses (mass numbers, symbol 'A') of isotopes differ. This affects physical properties such as densities and temperatures of...
What is the definition of an isotope? Isotopes: Isotopes are species of the same atom: The species differentiate themselves for their masses. That means that the nuclei weigh differently in each species. The above is due to differences in neutron number. ...
