Chapter 5 sect. 1&2

dumb vocab words

is a form of energy that exhibits wavelike behavior as it travels through space electromagnetic radiation
is the shortest distance between equivalent points on a continous wave wavelength
is the number of waves that pass a given point per second frequency
of a wave is the wave's height from the origin to a crest, or from the origin to a trough amplitude
also called the EM spectrum, encompasses all forms of electromagnetic radition, with only differences in the types of radiation being their frequencies and wavelengths electomagnetic spectrum
the minimum amount of energy that can be gained or lost by an atom quantum
has a value of 6.626 X 10-34 J X s, J is the symbol for joule, the SI unit of energy Planck's constant
electrons, are emitted from a metal's surface when light of a certain frequency shines through the surface. photoelectric effect
a particle of electromagnetic radition with no mass that carries a quantum of energy photon
an element is the set of frequencies of the electromagnetic waves emitted by atoms of the element atomic emission spectrum
the lowest allowable energy state of an atom ground state
predicts that all moving particles have wave characteristics de Broglie equation
states that it is fundamentally imopossible to know precisely both the velocity and positon of a particle at the same time Heisenberg uncertainty principle
atomis model in which electrons are treated as waves is called the wave mechanical model of the atom os more commonly quantum mechanical model of the atom
indicate the relative sizes and energies of atomic orbitals principal quantum numbers
specifies the atom's major energy levels prinicpal energy levels
principal energy levels contain energy sublevels
