Question | Answer |
---|---|
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 |
