Radioactivity affects elements that are unstable and tend to break apart easily. These elements often have the largest atomic numbers on the periodic table. Explain how this relates to the behavior of the graph for the heaviest elements ( those on the right end of the graph) plz help THIS IS DUE TODAY

Athin, square metal plate measures 14 cm on each side and has emissivity of 0.60. the plate is heated to a temperature of 745°c. what is the rate at which the plate radiates energy ? the stefan-boltzmann constant is 5.67 × 10-8 w/(m2 ? k4). remember that the plate will radiate energy from both its top and bottom surfaces.

The law of conservation of energy states that energy cannot be created or , energy can be from one substance to another. the first blank is ' destroyed ' and for the second blank is ' transferred '
