In ratio, positive rays is_than that of cathode rays
Correct answer: A. Less
- A. Less
- B. Greater
- C. Equal
- D. Difficult to predict
Explanation
Positive rays are formed when high speed electrons collide with gas molecules and knock off there electrons making them positively charge, but not all gas molecules are ionized. Hence, the ratio of positive rays is less than cathode rays.

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.
