Dr. H wave model

Dr. Heiny: (Standard 01) Wave Mechanical Model

Bohr Model a model of the atom that shows electrons orbiting the tiny, positively charged nucleus of an atom in circular orbits
quantum mechanical model a model of the atom that describes the probability of finding an electron within a given space around the nucleus of an atom
s orbital the atomic orbital that is generally spherical in shape
p orbital the atomic orbital that is shaped like two raindrops that are tail to tail (or an airplane propeller).
d orbital the atomic orbital that is shaped like four raindrops with all four tails pointing toward a common center
Pauli exclusion principle no more than two electrons may occupy an atomic orbital, and only if the electrons have opposite spins
Hund's rule if more than one orbital in a subshell is empty, electrons will fill an empty orbital before pairing
orbital diagram a model for showing the order in which electrons fill the various sublevels of the orbitals in an atom
Electron configuration a list of the occupied orbitals in an atom and the number of electrons they contain
electron dot diagram a model of an atom that uses the symbol for the element to represent the nucleus and inner electrons, and shows valence electrons as dots around the symbol
valence electrons the electrons in the outermost orbitals of an atom that strongly determine the properties of an element
Electromagnetic spectrum all the kinds of electromagnetic radiation that can be identified by differences in the frequencies and wavelengths
Wavelength the shortest distance between two points that are in phase on a wave
Frequency the number of complete waves that pass a point in a given amount of time
Amplitude the distance from the crest of a wave to the origin, or from a trough of the wave to the origin
Photoelectric effect when photoelectrons are emitted from the surface of a metal when exposed to light of a particular frequency
