the lowest allowable energy state of that electron
what is an electron’s excited state
when an electron gains energy and jumps to a higher energy level
what needs to happen for an electron to be excited
it needs to absorb energy
what is a wavelength
the shortest distance between equivalent points of a continuous wave
what is the unit for frequency
hertz
what is a waves amplitude
the height from the origin to a crest or trough
what is a baseline
the beginning of a wave- the middle
what is electromagnetic radiation
a form of energy that exhibits wave-like behavior as it travels
what is the speed of a wave
3.00*10^8
what is the wavelength of visible light
400-700
what spectrum is visible light
continuous
what kind of relationship is frequency and wavelength
inverse
what kind of relationship is frequency and energy
direct
what is the Planck theory
matter can gain or lose energy only in small specific amounts
what did Louis de broglie believe
that Planck’s theory seemed to give electrons the properties of a wave and a particle
what is the wave-particle duality
electrons can act like waves or particles
what is newtonian or classical mechanics
describes the behavior of visible objects at ordinary velocities
what is quantum mechanics
describes the behavior of extremely small particles traveling at velocities near that of light
what are the two things that give you a full description of an electron
location and velocity
what is Heisenberg’s uncertainty principle
it is impossible to know both the exact position and the exact momentum
what does the uncertainty principle treat the electron as
a particle
what did schrödinger do
develop a mathematical equation to describe an electron’s behavior

principal
what quantum number is represented by l
azimuthal
what quantum number is represented by m
magnetic
what quantum number is represented by s
spin
what does principle number describe
the electron’s energy level
what is the maximum number of electrons in any energy level
2n^2
what does the azimuthal level describe
the sub levels of an element
what value is the sub level s
0
how do you figure how many orbitals are in a sub level
divide the maximum amount of electrons by 2
what orbital is shaped like a sphere
the s orbital
what do electrons in an orbital have to have
opposite spins
what is an electron configuration
the arrangement of electrons in an atom
what is aufbau principle
electrons are added one at a time to the orbitals until all electrons are accounted for
what are the sub levels at the moment
s p d f
what is Pauli’s exclusion principle
no two electrons in an atom have the same statistics for the 4 quantum numbers
what is Hund’s rule
orbitals are filled one at a time with electrons spinning in the same directions
electrons of the same sub level occupy ___ orbitals
empty
what are the electrons in the outer level called
valence electrons
what are all the other electrons called
