bohr concluyó ¿qué pasa con los electrones?
they orbit the nucleus in fixed paths called orbitals.
orbitan el núcleo en trayectorias fijas llamados orbitales.
they are found in the nucleus with the protons.
se encuentran en el núcleo con los protones.
they are found outside of the nucleus in regions of probability called electron clouds.
se encuentran fuera del núcleo en regiones de probabilidad llamadas nubes de electrones.

Explanation:

Bohr's model of the atom proposed that electrons orbit the nucleus in fixed paths called orbitals. The second option is incorrect because electrons are not in the nucleus (protons and neutrons are). The third option describes the quantum mechanical model (electron clouds), not Bohr's.

Answer:

They orbit the nucleus in fixed paths called orbitals.
