WebNov 17, 2013 · Alligevel bliver fysikstuderende stadig undervist i Bohrs atommodel. Den er nemlig stadig fortrinlig til at fremstille atomet simpelt med en positivt ladet atomkerne og elektroner i kredsløb på forskellige energiniveauer. Tilmed spillede Bohrs atommodel også en vigtig rolle, da forskerne i CERN sidste år fandt Higgs-partiklen. WebBohr’s atomic model is very close to the atomic model that can be seen these days. In Bohr’s atomic model, electrons are in a given orbit. This model is also called a planetary …
