Radioisotopes are used to study chemical reactions because of the fact that they attach radioactive isotopes to certain atoms.<span> Tracer radioisotopes used to study chemical reactions in molecular structures by adding radioistopes to reactants and using the uptake compared to the original isotope. </span>
Answer:
Element in the same group have similar chemical properties.
3 cubic centimeters, Volume= density/ mass
When the iron is not bonded to anything the oxidation number is 0 but when it is bonded to a nonmetal it will be positive. All reactions in which the oxidation number changes are considered redox.
