Hace 10 horas · Bohr tomó como referencia un átomo de hidrógeno para seguir el modelo de Rutherford. Se comparó al átomo con el sistema solar, donde un núcleo inmóvil en el centro era rodeado por los electrones en órbitas definidas. Creía que a cada órbita se le asignaba una energía, siendo la de mayor energía, la órbita más externa al núcleo.
Hace 2 días · In 1913, the physicist Niels Bohr proposed a model in which the electrons of an atom were assumed to orbit the nucleus but could only do so in a finite set of orbits, and could jump between these orbits only in discrete changes of energy corresponding to absorption or radiation of a photon.
Hace 5 días · Bohr Atomic Model - Structure of Atom. Bohr Model of Atom was based on theories of wave motion. It considered that electron, while spinning, maintains its energy and does not cascade into the nuclei. Hence, unlike Rutherford's model, it correctly explained the stability of atom.

Hace 4 días · James Franck and Gustav Hertz conducted an experiment in 1914, which demonstrated the existence of excited states in mercury atoms. It confirms the prediction of quantum theory that electrons occupy only discrete, quantized energy states. This experiment supports Bohr model of atom.

Hace 3 días · Werner Karl Heisenberg ( pronounced [ˈvɛʁnɐ kaʁl ˈhaɪzn̩bɛʁk] ⓘ; 5 December 1901 – 1 February 1976) [2] was a German theoretical physicist, one of the main pioneers of the theory of quantum mechanics, and a principal scientist in the Nazi nuclear weapons program during World War II.
