Wavelength The distance between two consecutive peaks or troughs in a wave
Frequency The number of waves (cycles) per second that pass a given point in space
Photon A particle of electromagnetic radiation
Excited State Energy has been absorbed
Ground State Least amount of energy possible
Quantized Energy Levels Only certain values of atoms are allowed
Bohr Model Electrons must orbit like planets
Wavelength Mechanical Model Electrons are moving in unpredictable ways around the nucleus
Orbitals Regions of space with a 90% probability of finding an electron
Pauli Exclusion Principal 2 electrons per orbital and only if spins are opposite
