The answer to the second question is no. No one can tell when a particular atom of a radioactive substance will decay. However, when we are dealing with large numbers of radioactive atoms we can predict how long it will take for a certain number or percentage of the atoms to decay. For each radioactive isotope, we can predict a certain half-life.
Radioactive decay is a random process at the single- atom level; is impossible to predict exactly when a particular atom will decay. However, the chance that a given atom will decay is constant over time.
