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.
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.
Democritius's model of the atom-that it was an indivisible-was accepted for quite a long time. However in 1940 the layout of the electrons, protons and neutrons were worked out by Maria Goeppert-Mayer, Eugene Wigner etc. so a model that the questioner is probably imagining as the 'accepted one' could be created. However since the electrons, protons and neutrons are made of quarks-discovered in 1964, another model of the atom was discovered.
Before Rutherford, scientists assumed that the atom was a single particle. Rutherford presented his revolutionary, physical atomic model that suggested an atom consists of a central charge (the term 'nucleus' was coined after Rutherford's model was presented) that is surrounded, presumably, by a cloud of orbiting electrons. He showed that most of an atom's mass was located in the atom's nucleus. Rutherford's model was later improved upon by Niels Bohr, father of the Bohr-model. Rutherford made no connection to an element's atomic number and the number of protons within an atom's nucleus; however, his atomic model paved the way for the discovery of this correlation only a couple years after his model was designed.
Atomic radius refers to the size of an atom, while model radius is the size of the atom as represented in a molecular or atomic model. In most models, the model radius is larger than the atomic radius in order to make the structure more visible and distinguishable. The relationship between the two is that the model radius is typically proportional to the atomic radius but scaled up for clarity.
Now the quantum model is accepted.
Today the accepted atomic model is quantic.
Bohr assumed that electrons moved in fixed orbits.
True
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 is the scientist whose model of the atom is now accepted as the most accurate atomic structure. His Bohr model, which incorporates quantized energy levels and elliptical orbits for electrons, was a significant advancement in understanding atomic structure.
The fluid mosaic model is currently the most accepted model of the plasma membrane. It describes the plasma membrane as a dynamic structure composed of a lipid bilayer with embedded proteins that are able to move and interact within the membrane.
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.
The currently accepted hypothesis of membrane structure is the fluid mosaic model. This model describes the cell membrane as a dynamic structure composed of a lipid bilayer with embedded proteins that are free to move laterally within the membrane. It emphasizes the fluidity and flexibility of the membrane.
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.
