Which option would be an appropriate model of nuclear fission=
Responses:
taking a teaspoon of sugar from a bowl
dividing a stack of paper equally between two people
disturbing a drop of water such that it breaks into smaller droplets
cutting a cake in half

The option that would be an appropriate model of nuclear fission is:
disturbing a drop of water such that it breaks into smaller droplets.
This analogy captures the idea of a larger nucleus breaking apart into smaller nuclei, similar to how a drop can split into smaller droplets.
The process of radioactive decay is unpredictable and irreversible. Which option would be an appropriate model of the radioactive decay of a group of atoms
Responses:
throwing tennis balls over a fence
breaking off pieces of wet clay
popping a bag of popcorn
petals falling from a flower

petals falling from a flower
The option that would be an appropriate model of the radioactive decay of a group of atoms is:
petals falling from a flower.
This analogy conveys the idea of an unpredictable and irreversible process, where petals (representing atoms) fall off over time without a specific pattern or predictability.
Which statement best describes the effect of radioactive decay on a nucleus
Responses:
The resulting nucleus is more stable than the original nucleus. The nucleus must be of the same element as the original.
The resulting nucleus is less stable than the original nucleus. The nucleus can be of a different element than the original.
The resulting nucleus is more stable than the original nucleus. The nucleus can be of a different element than the original.
The resulting nucleus is less stable than the original nucleus. The nucleus must be of the same element as the original.

The resulting nucleus is more stable than the original nucleus. The nucleus can be of a different element than the original.
The resulting nucleus is less stable than the original nucleus. The nucleus must be of the same element as the original.
The statement that best describes the effect of radioactive decay on a nucleus is:
The resulting nucleus is more stable than the original nucleus. The nucleus can be of a different element than the original.
Radioactive decay results in the transformation of an unstable nucleus into a more stable configuration, often resulting in a nucleus of a different element.
