electromagnetic radiation
A form of energy that exhibits wave like behavior as it travels through space
wavelength
The shortest distance between corresponding points or adjacent waves
frequency
The number of waves that passed through a certain point in specific time. Usually one second.
amplitude
a waves height from origin to crest
photon
a particle of EM radiation having zero mass and carrying a package of energy
ground state
The lowest energy state of an atom (all electrons are as close to the nucleus as you can get)
excited state
where the atom has a higher potential E than it has in its ground state (all electrons have extra energy by absorbing a photon)
atomic emission spectra
The emission spectrum of an element is the set of frequencies emitted by atoms of that element
quantum theory
describes mathematically, the waves properties of electrons and other very small particles
orbital
The 3-D region around the nucleus that indicates the probable location of electron
planck
he said there were packets of energy instead of continuous waves
einstein
packets of energy are moving in a wave ( do a wave particle nature of light )
bohr
A photon can come in and give e- energy enough to move up in orbit or two, then it can’t handle that orbit. It drops down to a lower orbit. it was wrong but made people think
de brogile
electrons as waves; his theory predicted that all moving particles have wave characteristics model explains the line emission spectra
heisenberg
is it possible to determine simultaneously both the position and velocity of an electron or any other particle?
Schrodinger
With the work of Heisenberg and debroglie, he developed an equation dealing with electrons as waves. It laid the foundation for modern quantum theory.
