WebbBohrs atommodell är den av Niels Bohr 1913 uppställda teorin för atomen enligt vilken elektronerna rör sig i cirkulära banor runt atomkärnan, där centripetalkraften ges av coulombkraften och rörelsemängdsmomentet är kvantiserat till ett heltal gånger Plancks konstant, nh/2π. Detta leder till att elektronen endast kan inta vissa specifika energinivåer.
