- What is binding energy?
Show answer
Energy required to disassemble a nucleus into its separate nucleons- What is mass defect?
Show answer
Difference between the sum of separated nucleon masses and the actual nucleus mass- At which nucleus does binding energy per nucleon reach its maximum?
Show answer
Iron-56 (Fe-56)- What does the semi-empirical mass formula predict?
Show answer
Nuclear masses based on liquid drop model with quantum shell effects- What is the strong nuclear force?
Show answer
Attractive force between nucleons with very short range, approximately 2 femtometers- What are magic numbers in nuclear physics?
Show answer
Nucleon numbers (2, 8, 20, 28, 50, 82, 126) where nuclei have closed shells and extra stability- What is alpha decay?
Show answer
Nucleus emits an alpha particle (helium-4), decreasing mass number by 4 and atomic number by 2- What is beta-minus decay?
Show answer
Neutron converts to proton, emitting an electron and electron antineutrino- What is beta-plus decay?
Show answer
Proton converts to neutron, emitting positron and electron neutrino- What is gamma decay?
Show answer
Nucleus emits high-energy photon when transitioning from excited state to lower energy state- What is half-life?
Show answer
Time required for half of a radioactive sample to decay- What is the decay constant lambda?
Show answer
Constant in exponential decay N(t) = N_0 * e^(-lambda*t), related to half-life by lambda = ln(2)/t_half- What is activity?
Show answer
Rate of radioactive decay, measured in becquerels (decays per second)- What is the Q-value in a nuclear reaction?
Show answer
Energy released or absorbed in reaction, Q = (initial mass - final mass) * c^2- What is nuclear fission?
Show answer
Process where a heavy nucleus splits into two lighter nuclei, releasing energy
