Can we predict when a single atom of a radioactive isotope will decay? Explain.
No. Radioactive decay- random process-spontaneously. Half-life give the time of half of a sample to decay, doesn't allow us to predict future of decay event.
How do alpha and beta decay differ from artificial transmutations?
Both occur spontaneously, while artificial transmutations are manmade.
Compare nuclear fission & fusion.
Fisson/fusion both nuclear reactions. Fission- splitting 2 or more smaller nuclei. Fusion- releases more energy than fission does.
