The decrease in the atomic number is not observed in case of________________?
Correct answer: B. β-emission
- A. Electron capture
- B. β-emission
- C. α-emission
- D. Positron emission
Explanation
In beta-minus emission, a neutron changes into a proton, so the atomic number increases by one while the mass number remains unchanged. Electron capture, positron emission, and alpha emission all decrease atomic number.
