Modelo de Bohr-Sommerfeld.

Modelo de Bohr-Sommerfeld. Niels Bohr (1855-1962). 1913. Modelo planetario. ¿Qué pasa con los electrones al interior del átomo?. Los electrones en los átomos están cuantizados, es decir no pueden tener cualquier valor de energía sino sólo ciertos valores específicos de energía.

The Atomic Model

The Atomic Model. An atom is the smallest component of an element that retains the characteristics of the element. Define: Atom. If you broke apart any one atom, it would be made of three parts- and it wouldn ’ t be the atom anymore. Atoms are made from three different sub-atomic particles:.
