Question | Answer |
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 |
