Rutherford's experiment led to the discovery of
Correct answer: A. Nucleus
- A. Nucleus
- B. Electron
- C. Proton
- D. A-particle
Explanation
Rutherford's famous gold foil experiment in 1909 provided crucial insights into the structure of the atom. In this experiment, alpha (α)-particles were directed at a thin gold foil. Most of the alpha particles passed through the foil, but some were deflected at various angles, and a small fraction even bounced back.The unexpected deflections and backscattering of alpha particles led Rutherford to propose that the atom has a small, dense, positively charged center, which he called the "nucleus." This nucleus contains most of the atom's mass and is surrounded by electrons orbiting at a distance.

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.
