Ch. 5 EMR equations

equations and scientists involving the quantum theory of electrons
Energy of a quantum
E quantum = hν
Energy of a photon
E photon = hν
de Broglie equation
λ=h/mv. the variable λ is wavelength, the variable h is planck's constant, the variable m is mass of the particle and the variable v is frequency
aufbau principle
an electron occupies the lowest-energy orbital that can receive it
Pauli exclusion principle
a maximum of two electrons may occupy a single atomic orbital, but only if the electrons have opposite spins
Hund's rule
one electron per orbital of equivalent energy before doubling up
