The appropriate model of the radioactive decay of a group of atoms would be "petals falling from a flower."
The appropriate model of the radioactive decay of a group of atoms would be the option of petals falling from a flower. To understand why this option is the most appropriate, let's consider the characteristics of radioactive decay.
Radioactive decay is an unpredictable process because it occurs randomly at the atomic level. We cannot predict exactly when a specific atom will undergo decay. In the context of the options given, the falling of petals from a flower represents this unpredictable nature. Each petal falls independently and at different times, just like the decay of individual atoms.
Radioactive decay is also irreversible, which means that once an atom decays, it cannot change back to its original state. In the case of petals falling from a flower, once a petal falls, it is not possible for it to return to its previous position on the flower.
In contrast, the other options provided, such as popping a bag of popcorn, breaking off pieces of wet clay, or throwing tennis balls over a fence, do not accurately represent the essential characteristics of radioactive decay. These activities can be predictable, reversible, or both. For example, popping a bag of popcorn can be predictable because we can estimate the time it takes for all the kernels to pop, and it is also reversible because we can unpopped kernels to pop again.
Therefore, the most appropriate model of the radioactive decay of a group of atoms is the option of petals falling from a flower.
