In this lesson our instructor talks about structure of atoms. First, he discusses electromagnetic radiation, atomic spectroscopy, and the Bohr model. Then he talks about the wave nature of matter, quantum mechanics, and the shape of atomic orbitals. He ends the lesson with a summary and two helpful sample problems.
Light is a form of electromagnetic radiation which can be described by its energy, wavelength, and frequency.
The Bohr Model, which gives a simplistic view of photoemission, incorrectly assumed that electrons traveled in fixed, circular orbits around the nucleus.
The advent of quantum mechanics resulted from the idea that matter has both a wave-particle nature.
Heisenberg’s Uncertainty Principle states that we can never know the exact location of a moving electron.
Schrodinger helped develop wavefunctions, giving rise to the concept of the atomic orbital.
