The series of hydrogen spectrum in ultraviolet region is:

The series of hydrogen spectrum in…

Answer: Lyman.

A Balmer
B Paschen
C Lyman
D Brackett

Correct answer: C. Lyman

Explanation: Lyman series: transitions to n=1. These photons are in the ultraviolet range. Balmer series (visible) transitions to n=2.

Comparison of the Thomson model and the Rutherford model of the atom: in the Thomson plum pudding model alpha particles pass almost straight through a diffuse positive sphere, while in the Rutherford model a concentrated central nucleus deflects some alpha particles through large angles, with the lower panels showing the alpha particle source and gold foil and the observed result of wide-angle scattering

The Geiger–Marsden alpha-scattering result: a few alpha particles bounce back at large angles, which rules out Thomson’s diffuse model and demands a tiny, massive, positively charged nucleus. Image: Kurzon, CC BY 3.0, via Wikimedia Commons.

Concept context

Thomson's plum-pudding model, Rutherford's nuclear model from alpha-scattering, Bohr's postulates and hydrogen spectrum, spectral series (Lyman to Pfund), Rydberg formula, and limitations of each model.
