Chemistry in a Nutshell

Unlock the secrets of the Bohr model of the atom! In this video, you'll learn how electrons occupy energy levels, how they jump between orbits, and how those transitions produce the colorful hydrogen emission spectrum.

Perfect for general chemistry students, this clear explanation covers:

0:00 The Problem with Rutherford's Planetary Model

1:08 Bohr's Questions

2:06 Planck & Einstein's Quantized Energy

3:50 Bohr's Atomic Model

4:43 Atomic Emission Spectra Explained

5:55 Lyman, Balmer, & Paschen Series

6:22 Rydberg Constant, Equations, & Groundbreaking Findings

OpenStax Chemistry 2e, Figure 6.13 Compare the two types of emission spectra: continuous spectrum of white light (top) and the line

spectra of the light from excited sodium, hydrogen, calcium, and mercury atoms. Continuous spectrum and emission spectrum of calcium were used to show continuous and discrete spectra of a rainbow.
