This project was preformed to supply Libretext Authors with videos on General Chemistry topics which can be used to enhance their projects. Also, these videos are meant to act as a learning resource for all General Chemistry students.
Video Topics
Rutherford’s model of a nuclear atom does not indicate how electrons are arranged. In 1913 Niels Bohr explained how an electron can orbit a hydrogen (1 e-) atom. 1) Electrons move in circular orbits about the nucleus. 2) Electrons have only a fixed set of allowed orbits, called stationary states. The energy the electron has at each of these states is related to the equation. En = -Rh / n2. Where Where Rh = 2.18 x 10-18 J and n is an integer value: 1, 2, 3, 4... The variable n is related to the distance the electron is away from the nucleus. These concepts allow for the calculation of the wavelength of photon ejected when an electron drops from a higher n to a lower n value. Also, when a photon is absorbed the new n value of an electron can be calculated. This video contains a sample problem, which involves these concepts.
