Why must the final product of a decay series be stable? the daughter isotope of any radioactive decay is stable. no decay chain can emit more than two particles. each decay results in a net loss of particles. if the daughter isotope is unstable, it will decay.

If the daughter isotope is unstable, it will decay.

Explanation:

Radioactive decay process is a type of process in which a less stable nuclei decomposes to a stable nuclei by releasing some radiations or particles like alpha, beta particles or gamma-radiations. The radioactive decay follows first order kinetics.

The less stable nuclei is called the parent nuclei and the resulting nuclei is called as the daughter nuclei.

Thus if the daughter nuclei is stable it would not decay further and a decay series takes place in which each subsequent nuclei decays until a stable nuclei is finally produced.

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
