- Why is the answers I put not right ?An isotope of a radioactive element has half-life equal to 9 thousand years. Imagine a sample that is so old that most of its radioactive atoms have decayed, leaving just 25 percent of the initial quantity of the isotope remaining. How old is the sample? Give your answer in thousands of years, correct to one decimal place.MEECHYBABY &N Global Trade: Tutorial A f2. app.edmentum.com/courseware-delivery/ua/49021579/45266906/aHR0cHM6Ly9mMI5hcHAuZWRtZW50dWouY29tL2xİYXJuZXItdVe Global Trade: Tutorial Question Select the correct answer.
