Mass defect and binding energy

Mass defect and binding energy

An atomic nucleus contains protons and neutrons, called nucleons. In nuclear notation, proton number is ZZZ and nucleon number is AAA. If you add the masses of the separate nucleons, the total is slightly larger than the actual mass of the bound nucleus.

Step-by-step lessons on Edexcel A Level Physics Binding energy, fission and fusion. Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks across the three papers require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
