Question

Carbon-14 ( C ) decays via decay and emits an electron and an antineutrino. How many PROTONS (p) and NEUTRONS (n) are in the DAUGHTER nuclide? 5 p, 8 n p, n .p, n p, n .l, p,l n A neutral carbon-14 atom has a mass of 14.003242u. The neutral daughter atom produced in the decay of carbon-14 has a mass of 14.003074u. What is the MAXIMUM KINETIC ENERGY of the beta particle? 156 MeV 168 MeV 352 MeV 2.89 MeV 3.67 MeV A radioactive sample has a half-life of 50 days. What FRACTION of the sample remains after 10 days? 0.15 0.20 0.55 0.87 0.95

Explanation / Answer

(14, 6)C undergoes beta decay to become nitrogen with 7 proton and 7 nutrons

so option E) is correct
