Hydrogen atom does not emit X-rays because

Options

  1. Ait contains only a single electron
  2. Benergy levels in it are far apart
  3. Cits size is very small
  4. Denergy levels in it are very close to each other

Correct answer

D. energy levels in it are very close to each other

Step-by-step solution

Hydrogen atom does not emit X-rays because its energy level are very close to each other. Hence, the transition of electron emits high energy radiations having short wavelength.
