What is the symbolic representation used to denote an isotope, where A represents the number of nucleons, Z represents the number of protons, and X represents the atomic symbol?
What is the symbolic representation used to denote an isotope, where A represents the number of nucleons, Z represents the number of protons, and X represents the atomic symbol?
- X - Z = A
- A Z X (correct)
- A + Z = X
- A/Z/X
What is the equation used to represent the isotope production process, where A, Z, X represent the target isotope, A’, Z’, X’ represent the product isotope, and Pi represents the bombarding particle?
What is the equation used to represent the isotope production process, where A, Z, X represent the target isotope, A’, Z’, X’ represent the product isotope, and Pi represents the bombarding particle?
- A - Z - X - Pi - Pe = A' + Z' + X'
- A Z A' e Z' X ( Pi , P ) X ' (correct)
- Pi - Pe = A' / Z' / X'
- A + Z + X + Pi = A' + Z' + X'
