5. Compared with other types of particles emitted by naturally occurring radioactive elements, gamma rays have a Select all of the correct answers: higher penetrating power then beta particles lower mass than alpha or beta particles higher ionizing power than alpha particles higher ionizing power than beta particles higher penetrating power than alpha particles 6. Beta decay of an unstable nucleus produces a particle that is identical to \( a(n) \) Enter the correct word or phrase: 7. When an atom undergoes alpha decay, Select all of the correct answers: the atomic mass increases by 1 the atomic number decreases by 2 the atomic mass decreases by 4 the atomic number increases by 1 the atomic mass in unchanged 8. Due to the binding energy of the nucleus and electrons, the mass of every atom is Select only the best answer: exactly the same as the masses of its constituent protons, neutrons and electrons. slightly greater than the masses of its constituent protons, neutrons and electrons. slightly less than the masses of its constituent protons, neutrons and electrons. 1. Tritium \( \left({ }^{3} \mathrm{H}\right) \) has a half-life of \( 12.3 \) years. If a \( 360.0 \mathrm{~kg} \) sample of tritium is allowed to age for \( 24.6 \) years, what mass of the original sample remains unreacted? Include at least 3 sianilficant fipures in your answer. \( \mathrm{kg} \) 2. When \( { }^{30} \mathrm{P} \) undergoes positron emission, the decay products are Select only the best answer: \[ \begin{array}{l} 30 \mathrm{~s}+\mathrm{e}^{+} \\ 31 \mathrm{~S}+\mathrm{e}^{+} \\ { }^{31} \mathrm{Si}+\mathrm{e}^{+} \\ 30 \mathrm{si}+\mathrm{e}^{+} \\ 31 \mathrm{P}+\mathrm{e}^{+} \end{array} \] 3. A type of natural radioactivity called Enter the correct word or phrase: decay occurs when an unstable nucleus emits a particle consisting of two neutrons and two protons (i.e., a helium nucleus). 4. When a \( { }^{228} \mathrm{U} \) atom undergoes alpha decay, the atomic mass of the resulting thorium atom is Enter the value with the appropriate number of significant figures. amu 9. When a \( { }^{227} \mathrm{Ra} \) atom undergoes alpha decay, the atomic mass of the resulting radon atom is Enter the value with the aobrooriate number of signiticant figures. \( \mathbb{1} \) amu 10. Nuclear fission is a process when two nuclei of an atom combine to form a heavier atom, while nuclear fusion is the splitting of a nucleus into two lighter particles. Select true or tilse: True False
