Question
Which of the following processes causes the emission of X-ray?(a) $\alpha$ -emission(b) \beta-emission(c) $\beta^{+}$ (Positron emission)(d) electron capture
Step 1
X-ray emission occurs when an electron from a higher energy level in an atom falls to a lower energy level, closer to the nucleus. The difference in energy between the two energy levels is emitted as an X-ray. Show more…
