92 U 235 is (alpha) active. then in large quantity of the element (a) the probability of a nucleus disintegrating during one second is lower in the first half life and greater in the fifth half life. (b) the probability of a nucleus disintegrating during one second remains constant for all time. (c) quite an appreciable quantity of U235 will remain even after the average life (d) the energy of emitted alpha particle is less than the disintegration energy of U235 nucleus expert.. could u please explain to me the question as well. what is alpha active??? and the soln too.. thanks.
