Study Notes
Nuclear Emission and Decay
- Gamma rays are emissions often excluded from nuclear equations as they do not alter charges, atomic numbers, or mass numbers.
- Alpha particles, consisting of two protons and two neutrons, produce nuclei akin to helium during decay.
Radium to Radon Decay
- The decay of radium (226/88Ra) produces radon (222/86Rn) and an alpha particle (4/2He), identified as alpha decay.
Gold Transmutation
- Gold undergoes transmutation represented by the equation 185/79Au -> 181/77Ir + 4/2He, a process classified as alpha decay.
Helium Decay
- Helium can decay into lithium, as shown in the equation 6/2He -> 6/3Li + 0/-1e, which is categorized as beta minus decay.
Oxygen to Nitrogen Decay
- The decay of oxygen into nitrogen is represented by 15/8O -> 15/7N + 0/1e, classified as beta plus decay.
Mercury-203 Decay
- In beta minus decay, mercury-203 (203/80Hg) transforms into thallium (203/81Tl) while emitting an electron (0/-1e).
Potassium to Calcium Decay
- In a specific beta decay, potassium is denoted with values a = 19, b = 40, c = -1, representing beta minus decay.
Bombarding Plutonium
- Bombardment of plutonium-239 (239/94Pu) with an alpha particle yields curium with a balanced equation of 239/94Pu + 4/2He → 242/96Cm + 1/0n.
Neutron Collision with Nitrogen
- The collision of a neutron with nitrogen yields a transmutation represented as 1/0n + 14/7N -> 14/6C + 1/1H.
Radioactive Nuclide Notation
- The symbol for a radioactive nuclide includes both the atomic number and the mass number for identification.
Balancing Nuclear Equations
- Missing values in equations can be identified to ensure conservation of charge and nucleons, such as the equation 22/11Na -> 22/10Ne + 0/(+1)B.
Radioactive Nuclide Symbols
- The radioactive nuclide with 15 protons, 15 electrons, and 17 neutrons is represented as 32/15P.
- A nuclide characterized as 234/90Th has an atomic number of 90.
Decay Resulting Nuclides
- The decay equation 235/92U -> 231/90Th + 4/2He identifies the nuclide X as 231/90Th.
- A nuclide 64/29Cu that absorbs a positron results in the formation of 64/30Zn.
Completing Nuclear Equations
- The unbalanced equation 124/56Ba -> 124/55Cs + ? is completed by 0/+1e, indicating positron emission.
