that depends on what level of chemistry your taking. they teach the bohr model in high school, and sometimes in college they teach quantam mechanics. it depends on who you ask.
The quantic model is accepted today.
Bohr assumed that electrons moved in fixed orbits.
The currently accepted atomic model is the Electron Cloud model. It is more accurate than the Bohr model because what Niels Bohr did not know was that electrons weren't always in perfect alignment in perfect orbit around the atomic nucleus. The Electron Cloud model shows that electrons do not have to be perfectly aligned around the nucleus in specific energy level 'rings' as the Bohr model showed.
A Chadwick atomic model doesn't exist.

The current model of an atom is called the Bohr model.
Now the quantum model is accepted.
Bohr assumed that electrons moved in fixed orbits.
Today the accepted atomic model is quantic.
True
The fluid mosaic model, of corse!
Heliocentric: It is the model that states that the sun is in the center of our solar system.
Dalton's atomic theory or model was accepted despite errors. This is because his theory provided a logical explanation of concepts and led the way to new experimentations.
Bohr assumed that electrons moved in fixed orbits.
Niels bohr
The "plum pudding" atomic model of J. J. Thomson is considered today simplistic and incorrect; now is accepted the quantum atomic model, more realistic but also more complicate.
They developed the currently accepted model of the plasma membrane of a cell in 1972 at the University of California, San Diego. Their model is called the Fluid-Mosaic Model.
First of all he did'nt say that it was invisible, he said it was indivisible i.e. it cannot be divided further but it can be in the form of protons,electrons and neutrons.That's why it was not accepted. By the way he proposed atomic theory not a model. Models were proposed by THOMSON, RUTHERFORD and NEIL BOHR.
