23.1.7—The energy released in nuclear reactions using E = c 2∆m

calculate the energy released in nuclear reactions using E = c 2∆m.

Use —the energy released in nuclear reactions using e = c 2∆m to connect the rule to the data and decision in the question.

This matters because —the energy released in nuclear reactions using e = c 2∆m determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —the energy released in nuclear reactions using e = c 2∆m to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —The energy released in nuclear reactions using E = c 2∆m is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
