CHEM 101 Chapter Notes -Potential Space, Pauli Exclusion Principle, Valence Electron
Document Summary
Wavelength is the distance between two consecutive wave peaks: represented by a lowercase lambda. Frequency is indicated by how many wave peaks pass a certain point per given time period. Another way to think of a beam of light traveling through space is a stream of tiny packets of energy called photons. Ground state is the lowest possible energy state of an atom. Different wavelengths of light carry different amounts of energy per photon. The energy contained in the photon corresponds to the change in energy that the atom experiences. Energy levels of hydrogen are quantized, that is, only certain values are allowed. Energy levels of all atoms are quantized. Bohr constructed a model of the hydrogen atom with quantized energy levels that agreed with hydrogen emission results. Electrons do not move around the nucleus in circular orbits. Wave mechanical model the electron states are described by orbitals.
