Today's atomic model

WebbDalton's ideas proved foundational to modern atomic theory. However, one of his underlying assumptions was later shown to be incorrect. Dalton thought that atoms were the smallest units of matter −-− minus tiny, hard spheres that could not be broken down any further. This assumption persisted until experiments in physics showed that the atom … 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.
