CHE 201 Lecture Notes - Lecture 15: Subatomic Particle, Atomic Orbital, Standing Wave
Document Summary
Chapter 6 quantum theory and the electronic structure of atoms. According to de broglie, an electron in an atom behaves like a standing wave. However, only certain wavelengths are possible or allowed. The relationship between the circumference of an allowed orbit (2 r) and the wavelength ( ) of the electron is given by: 2 r= v. By directing a beam of electrons through a thin piece of gold foil, thomson obtained a set of concentric rings on a screen, similar to the diffraction pattern observed when x rays were used. To describe the problem of trying to locate a subatomic particle that behaves like a wave, werner heisenberg formulated what is now known as the. The probability of finding the electron in a certain region in space is proportional to the square of the wave function, 2. The quantum mechanical description of the hydrogen atom.
