A small amount of solution containing a radioactive nucleide `A""^(x)` was administrated into the blood of a patient. The activity of the nucliede id `2xx10""^(3)`dps. Its half life is 15 hours. After 5 hours a sample of the blood drawn out from the patient. It,s activity was 16 dpm per mL. In the following graph, binding energy per nucleon is plotted against mass number (a). three elements `A_(1),A_(2)and A_(3)` are located in the graph. Select the false statement about the graph. A. elment `A""_(2)` is more stableB. element `A""_(3)` is less stable than `A""_(2)`C. element `A""_(1)` is more stable than both `A""_(2)` and `A""_(3)`D. `A""_(2)` is metallic element |
