the planetary model
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.
For a while, but eventually a new atomic model came out that we still use today.
The usual idea of the atomic model is a nucleus composed of protons and neutrons, surrounded by electrons in orbit in shells of increasing diameter. This helps to visualise the difference between atoms. Quantum theory is that this simple model is not accurate, but it does have the virtue of being easily understood.
Experiments like the photoelectric effect and atomic emission spectra provided evidence that electrons exist in discrete energy levels. These findings challenged the classical model of the atom, leading to Niels Bohr proposing his model in 1913 to explain the quantization of electron energy levels in atoms.
Atomic models tell us about the structure of an atom which is based on what we know about how atoms behave. But it is not necessary that it will be a genuine picture of the structure of an atom.
The Bohr model!
The Bohr model of the atom, the theory that electrons travel in discrete orbits around the atom's nucleus.The shell model of the atom, where the chemical properties of an element are determined by the electrons in the outermost orbit.The liquid drop model of the atomic nucleus.Identified the isotope of uranium that was responsible for slow-neutron fissionThis answers came from wikipedia

The first atomic model based on experimentation was developed by J.J. Thomson in 1897. Thomson's model, known as the "plum pudding model," proposed that atoms were made up of a positively charged material with negatively charged electrons scattered throughout, similar to the seeds in a watermelon.
