Who discovered positive rays (also called protons) and when?
Correct answer: B. Goldstein,1886
- A. Chadwick,1895
- B. Goldstein,1886
- C. Rutherford,1885
- D. J.Perrin,1885
Explanation
Option B is correct as Eugene "Goldstein" discovered positive particles by using a tube filled with hydrogen gas. This resulted in the positive particle that had a charge equal to and opposite to the electron. The positive particle was named the proton.

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.
