During a radioactive decay, which of the following statements is false
During a radioactive decay, which of the following statements is false
- A. atomic mass number cannot increase
- B. atomic number may increase
- C. atomic number may decrease
- D. atomic number will remain unchanged
Step-by-step solution
In radioactive decay, the atomic number can change: it increases in beta-minus decay and decreases in alpha decay, beta-plus decay, or electron capture. Therefore, the statement that atomic number will remain unchanged is false.
