H1 Physics: Nuclear Physics structured questions

Learning objectives

• Interpret nuclear structure, isotopes and Rutherford scattering.
• show an understanding that an element can exist in various isotopic forms, each with a different number of neutrons in the nucleus, and use the notation ZA X for the representation of nuclides
• state that one mole of any substance contains 6.02 × 1023 particles and use the Avogadro number NA = 6.02 × 1023 mol-1
• show an understanding of the spontaneous and random nature of nuclear decay, and use the term activity
• Analyse random radioactive decay, activity, decay constant and half-life.
• define half-life as the time taken for a quantity x to reduce to half its initial value, and use the term to solve problems which might involve information in tables or decay curves
• Relate binding energy per nucleon to fission, fusion, applications and hazards.
• represent simple nuclear reactions by nuclear equations of the form 147 N + 4 2 He → 178 O + 11H
• Apply conservation laws to nuclear equations and beta decay, including antineutrino evidence.
• Use mass-energy equivalence, mass defect and binding energy.
