Question

Which of the following statements is false? O Radionuclides with high neutron-proton ratios will decay by beta radiation. O The non-radioactive isotopes have neutron-proton ratios that fall with in the "beit of stability O The neutron-proton ratio of an isotope is an important factor in determining stability of a nuclide. O Radionuclides with low neutron-proton ratios will decay by beta radiation. A freshly prepared sample of an unknown isotope of potassium has an activity of 4.6x 105 disintegrations per minute (dpm). After 170 days, the activity of the sample declines to 7.8 x 104 dpm. The half-life of this radioisotope of potassium is how many days? 0 29 0 36 0 58 0 41 0 66
