Chapter 5.1 and 2

Electromagnetic radiation a form of energy that exhibits wavelike behavior as it travels through space.
Wavelength the shortest distance between equivalent points on a continuous wave.
Frequency the number of waves that pass a given point per second.
amplitude the wave's height from the origin to a crest, or from the origin to a trough.
electromagnetic spectrum encompasses all forms of electromagnetic radiation
quantum the minimum amount of energy that can be gained or lost by an atom
Planck's constant 6.26 x 10^-34J*s, where J is the symbol for Joule
photoelectric effect electrons that are emitted from a metal's surface when light of a certain frequency shines on the surface.
photon a particle of electromagnetic radiation with no mass that carries a quantum of energy.
atomic emission spectrum the set of frequencies of the electromagnetic waves emitted by atoms of the element.
ground state the lowest allowable energy of an atom
de Brogile equation predicts that all moving particles have wave characteristics
Heisenberg uncertainty principle states that it is fundamentally impossible states that it is fundamentally impossible to know precisely both the velocity and position of a particle at the same time.
quantum mechananical model of the atom the atomic model in which electrons are treated as waves
atomic orbital a three-dimensional region around the nucleus
principal quantum numbers indicate the relative sizes and energies of atomic orbitals.
principal energy levels the atom's major energy levels
energy sublevels The energy levels contained within a principal energy level.
