Which statements best describe half-lives of radioactive isotopes? Check all that apply. The half-life varies depending on the isotope. The half-life is the same for every isotope. Half-lives are always only minutes long. Half-lives range from fractions of a second to billions of years. The half-life of a particular isotope is constant. The half-life of a particular isotope changes constantly.

I think the correct answers are the  half-life varies depending on the isotope, half-lives range from fractions of a second to billions of years and  half-life of a particular isotope is constant. Half-life is a constant value for a specific isotope that tells when does the mass of the isotope reduces to half of the original mass. Hope this helps.
