is aform of energy that exhibits wavelike behavior as it travels hrough space. | electromagneti radiation |
is the shortest distance between equivalent points on a contiuous wave. | wavelenght |
is the nuumber of waves that pass a given point per second. | frequency |
is the wave's height from the orivin to a crest, or from the origin to a trough. | amplitude |
called the EM spectrum, encomppasses all forms of electromagnetic radiation, with the only differences in the types of radiatoin being their frequencies and wavelenghts. | electromagnetic spectrum |
is the minimum amount of energy that can be gained or lost by an atom | quantum |
where J is the symbol for the joule, the SI unit of energy. | Planck's constant |
called photoelectons, are emitted form a meta's surace when light of a certain frequency shines on the surface. | photoelectric effect |
is a particle of electromanetic radiaton with no mass that carries quantum o0f energy. | photon |
of 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 |
statres that it is fundamentally impossible to know precisely both the velocity and position of a particle at the same time. | Heisenberg uncertainty principle |
the otomic model in which electrons are treated as waves is called the wave mechnical model of the atom or more comonly the..... | quantum mechanical model of the arom |
A three-dimentional region around the nucleus. | atomic orbital |
indicate tyhe relative sizes and energies of atomic orbitals. | principal quantum number |
Atoms major energy levels | pricipal energy level |
Principal energy levels contain this strand of energy. | energy sublevel |
