QuestionAnswer
electronmagnetic radiation a form of energy that exhibits wavelike behavior as it traver through space
wavelength the shortest distance between equivalent points on a continuous wave
frequency the number of waves that pass a given point for a second
amplitude a wave heights from the orgin to a crest or from theorigin to a tough
electromagnetic spectrum encompasses all forms of electronmagnetic raditon
quantum the minimum amount of energy that can be grand or lost by an atom
Planck's constant has a value of [6.626x10^-34Jxs]
photoelectric effect are emitted from a metal's surface when light of a certain frequency shines on a surface
photon a particle of electronmagnetic radiation with no mass that carries a quantum of energy
atomic emission spectrum an element is the set of frequencies of the electromagnetic waves emitted by atoms of the element
ground state the lowest allowable energy state of an atom
de Broglie equation predicts that all moving particles have wave characteristics
heisenberg uncertainty principle states that it is fundamentally impossinle to know precisely both the velocity and position of a particle at the same time
quantum mechanical model of the atom atomic model in which electrons are treated as waves
atomic orbital a three dimensional regin around the nucleus
principal quantum number that indicates the relative sizes and energies of atomic orbitals
principal energy levels specifies the atoms energy level
energy sublevels the energy levels contained within principal energy level
