Rutherford's experiments on the scattering of α particles proved that
Correct answer: A. Atom is mostly empty
- A. Atom is mostly empty
- B. +ive charge is uniformly distributed in the atom
- C. Number of +ive charge is equal to the number of -ive charge
- D. Atoms contain electrons
Explanation
Correct. Rutherford's experiments showed that atoms have a mostly empty space.In summary, the correct option is **a. Atom is mostly empty** based on Rutherford's experiments.

About Atomic Spectra
Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
