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
