Fast moving electrons stopped by a heavy metallic target in an evacuated glass tube give rise to the:
Correct answer: C. X-rays
- A. Beta-rays
- B. Gamma-rays
- C. X-rays
- D. Cosmic rays
- E. Alpha-rays
Explanation
X-ray generation occurs when heated electrons are accelerated towards a tungsten target. Upon collision, these high-speed electrons produce X-rays through two main processes: Bremsstrahlung radiation, where electrons lose energy and emit X-rays, and characteristic X-rays, which arise when inner-shell electrons are displaced, prompting higher energy electrons to fall into lower energy levels and emit X-rays with specific energies. This process is fundamental to medical imaging and various industrial applications

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
