Unit 4 Electron Arrangement Test

characteristic properties of all waves frequency, wavelenght, speed, amplitude
at what speed to all electromagnetic waves travel in a vacuum 3x10^8 m/s
continuous spectrum of white light refracted into all colors
atomic emission spectrum each element has a certain spectrum- certain wavelengths+frequencies- each element has its own unique line spectrum
2 ways behavior of electrons can be described waves and particles
waves formula c= v times wavelength
particles formula E=hv
Heisenberg's Uncertainty Principle you cannot determine the position and momentum of an electron at the same time
4 quantum numbers principle qn, angular qn, magnetic qn, spin qn
3 rules for writing electron configurations Aufbau Principle, Poli exclusion principle, hund's rule
aufbau principle electrons enter 1 at a time to the lowest energy orbitals until all electrons have been accounted for
pauli exclusion principle an orbital can hold at most 2 electrons; 2 electrons must have different spins
hund's rule electrons occupy equal energy orbitals so that a max # of unpaired electrons result- dont pair up until they have to
