(a) Arrange the following in their correct order of increasing energy: alpha particles, gamma rays and beta particles
(b) State one difference between nuclear fission and nuclear fusion
Explanation
(a) Alpha particles, beta particles, gamma rays
in order of increasing energy
in terms of penetrating energy
(b) Difference between nuclear fission and nuclear fusion
Nuclear fission |
Nuclear fusion |
A heavy isotope of element is split into fragments of lighter elements by neurons bombardments of the heavy nucleus |
Lighter isotopes combine to give a heavier isotope E.g \(^2_1H + ^3_1H\) \(\to\) \(^4_2He\) + \(^1_0n\) |
