(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

(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 \(^2_1H + ^3_1H\) \(\to\) \(^4_2He\) + \(^1_0n\)
