QuestionAnswer
Electromagnetic Radiation form of enerygy that exhibits wavelike behavior as it travels through space
wavelenght tha shortest distance between equivalent points on a continuous wave
Frequency the number of waves that pass a given point per second
Amplitude the waves height from the origin to a crest, or from the origin to a trough
Electromagnetic Spectrum encompasses all forms of electromagnetic radiation, with the only difference in the types of radiation being their frequencies and wavelenghts
quantum the minimum amount of energy that can be gained or lost by an atom
Planck's Constant has a value of 6.626 x 10^-34, Where J is the symbol for the joule, the SI unit of energy
Photoelectric Effect are emitted from a metal's surface when light of a cartain frequency shines on the surface
Photon is a particle of electromagnetic radiation with no mass that carries a quantum of energy
Atomic Emission spectrum is the set of frenquencies of the electromagntic waves emitted by atoms of the element
Ground state lowest allowable energy state of an atom
de Broglie equation predicts all moving particles have wave characteristics
Heisenberg Uncertainty principle states that it is a fundamentally impossible to know precisely both the velocity and postion of a particle at the same time
quantum mechanical model of the atom atomic model in which electrons are treated as waves
atomis orbital a three dimensional region around the nucleaus
Principal Quantum numbers the relative sizes and energies of atomic orbitals
Principal energy levels atoms major energy levels
energy sublevels part of the energy level
electron configuration arrangement of electrons in an atom
aufbau principal each electron occupies the lowest energy orbital avaliable
pauli exclusion principal states that a maximum of two electrons may occupy a single atomis orbital, but only if the electrons have opposite spins
hund's rule single electrons wioth the same spin must occupy each equal energy obital before additional electrons with oppostie spins can occupy the same orbitals
valence electrons electrons in the atom's outermost orbitals
electron dot structure consists of the elements symbol, which represents the stomic nucleus and inner level electrons surrounded by dots representing the atom's valence electrons.
