What is the decay constant of nobelium-259? 8.7 × 10–5 s–1 2.0 × 10–4 s–1 1.7 × 10–2 s–1 1.2 × 10–2 s–1 2 / 5 2) A Geiger counter is placed near a radioactive source and different materials are placed between the source and the Geiger counter. The results of the tests are shown in the table. What is the radiation emitted by the source? α and β α only β and γ α and γ 3 / 5 3) In a Geiger-Marsden experiment, why do the majority of α particles pass straight through the metal foil? Atoms have positively charged nuclei. Atoms are largely empty space. Atomic nuclei may contain neutrons. Atoms are electrically neutral. 4 / 5 4) Uranium-236 undergoes nuclear fission to produce barium-144, krypton-89 and three free neutrons. What is the energy released in this process? 191 MeV 84 MeV 3730 MeV 106 MeV 5 / 5 5) Three different radioactive nuclides P, Q and R each decay by three different successive emissions. P emits α α β Q emits α β β R emits β β β Which nuclide produces a final nucleus that has the same proton number as its starting nucleus and which the same nucleon number as its starting nucleus? Q has the same proton numberR has the same nucleon number P has the same proton numberR has the same nucleon number Q has the same proton numberP has the same nucleon number P has the same proton numberQ has the same nucleon number Your score is Restart quiz
