Diane, Timothy and Ira were having a discussion about isotopes and the tendency to react. Which do you suggest offers the best explanation? Diane felt that isotopes would react the same as the atoms of the same element since they had the same number of valence electrons. Timothy suggested that they would react the same since the isotope and the atom of the same element would have the same number of total electrons. Ira said that the isotopes would react different since the number of neutrons would vary and therefore the atomic mass of the isotopes versus the atom of the same element would be different.
