Concept explainers
Interpretation:
Half-life of the highest-atomic-numbered element 118 that is laboratory produced is measured in which unit has to be chosen from the given options.
Concept Introduction:
Radioactive nuclides undergo disintegration by emission of radiation. All the radioactive nuclide do not undergo the decay at a same rate. Some decay rapidly and others decay very slowly. The nuclear stability can be quantitatively expressed by using the half-life.
Radioactive decay happens naturally. This can also be done artificially in the laboratory by means of bombardment reaction.
