5.4.133 - Nuclear binding energy

Understand the concept of nuclear binding energy and be able to use the equation ΔE = c2Δm in calculations of nuclear mass (including mass deficit) and energy.

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

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

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

Boundary: - Nuclear binding energy is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
