CHEM 112 Chapter Notes - Chapter 7: Pauli Exclusion Principle, Lanthanide, Alkali Metal
Document Summary
Chapter 7 notes - atomic structure and periodicity. 7. 1 electromagnetic radiation: types of em radiation (wavelengths in meters) 7 10-4 10-2 1 102 104 gamma xrays. 7. 2 the nature of matter: max planck and quantum theory, energy is gained or lost in whole number multiples of the quantity hv. Planck"s constant = h = 6. 626 x 10-34 j s. E = nhv: energy is transferred to matter in packets of energy, each called a quantum, einstein and the particle nature of matter, em radiation is a stream of particles - photons hc, energy and mass are inter-related. E photon hv: de broglie and the dual nature of light. 2 mc: light travels through space as a wave, light transmits energy as a particle, particle"s have wavelength, exhibited by diffraction patterns h= mv, large particles have very short wavelengths, all matter exhibits both particle and wave properties.
