Scientists determined that electrons do not orbit the nucleus like planets. Instead, electrons can be anywhere in a cloud like region around the nucleus
the planetary model
The scientists often revise the hypothesis.

yep- pretty sure
Niels Bohr introduced the notion of electronic orbits.
It added on Niels Bohrs model and his research. And anika's cool :D
Niels Bohr proposed a "planetary system" model for the atom.
Bohr model explain these spectra.
The Bohr atomic model is similar to solar system.
Neil Bohrs atomic model is simply called Bohrs model. It states that electrons have a certain amount of energy, so they must follow certain orbits. This is different from the modern atomic model.
