It did not as well describe atoms with many electrons and molecules. Current research has, however, shown that some characteristics of many-electron atoms and molecules can be described with it. In the article dynamical scaling is explained that returned confidence to the old model and some results are quoted for the energy of the hydrogen molecule. The new approach stimulates simple ideas about the motion of electrons in atoms and moleculesPred sto leti je model Nielsa Bohra opisal vodikov atom z enim elektronom. Atomov z več elektroni in molekul ni opisal tako uspešno. Novejša raziskovanja pa so pokazala, da je mogoče z modelom opisati tudi nekatere lastnosti večelektronskih atomov in molekul. Članek pojasni dimenzijsko lestvičenje, ki je vrnilo zaupanje v stari model, in navede nekaj rezultatov za energijo vodikove molekule. Novi model spodbuja preproste nazorne predstave o gibanju elektronov v atomih in molekulahTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaDruštvo matematikov, fizikov in astronomov
