What do the bohr and quantum mechanical models have in common?

In both models, electrons move around a positively charged nucleus filling different energy levels called shells.  

Explanation:

Bohr's model places electrons in ascending energy levels orbiting in a circular motion around the nucleus. The quantum mechanical model also places electrons around a positively charged nucleus following ascending energy levels, but this time these don’t move in a circular manner but instead randomly inside clouds of probability.
