5.4.139 - Nuclear equations

Be able to write and interpret nuclear equations given the relevant particle symbols.

Use - nuclear equations to connect the rule to the data and decision in the question.

This matters because - nuclear equations determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - nuclear equations to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: use the formula and units given in the question, show the substitution and interpret the result; the calculation alone is not the conclusion.
