Why did the atomic theory change over time?
The atomic theory changed over time as new scientific discoveries and evidence emerged through experimentation. Early atomic theories were revised and refined to better explain the behavior of atoms and their interactions with each other. The development of more advanced experimental techniques also contributed to a better understanding of atomic structure and properties.
Who proposed the electron orbit model?
Niels Bohr proposed the electron orbit model in 1913 as an improvement to the previous model proposed by Ernest Rutherford. Bohr's model suggested that electrons orbit the nucleus in specific energy levels, which helped explain the stability of the atom.
What is the name of the scientist that developed the quantum mechanical model of the atom?
Erwin Schrodinger invented the model of the atom based on research done by scientists such as Niels Bohr.
Created the first accepted model of the atom?
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.
Have the models of atoms changed over the years?
The pretty universally accepted model from the time we first began to suspect (with some actual evidence, as opposed to being ancient Greeks pulling theories out a posteriori) that there were such things as atoms was that they were small, indivisible ... well, probably spheres. At least some of them were probably spheres, anyway.Around 1900 it became clear that while "small" was still true, "indivisible" was ... not so much. This lead to several competing theories that came out all about the same time (within a decade or so, anyway; 1902 to 1911): the cubic model, the "plum pudding" model, the "Saturnian" model, and the "Rutherford" model. All of these were attempts to explain the newly-discovered electrons and what exactly they were doing inside atoms.In 1913 Niels Bohr modified the Rutherford model a bit (incorporating some pieces of the Saturnian model as well) and came up with the Bohr model, which proposed that the electrons orbited a concentration of positive charge in the center of the atom in well-defined circular orbits. The Bohr model accounted for the fact that the electrons didn't immediately radiate energy and spiral into the nucleus by proposing that they were confined by ... something ... into specific orbits having characteristic energies. An electron could jump from one orbit to another (provided there was a space open), but only by giving off energy exactly equal to the difference in energy between the two orbits. This accounted for the observed phenomenon that atoms did in fact give off energy of very specific, or quantized, values.There were still problems with the Bohr model, one of which was that there didn't seem to be any particular reason the energy levels should happen to be what they were, so the Bohr model eventually disappeared in favor of the current quantum mechanical model, which describes the electrons as being in eigenstates of the time-dependent Hamiltonian equation, accounting precisely for their energies.

How does the model of the Atom change over time?

Why has our idea of what the atom looks like changed so many times?
Our idea of the atom has changed over time as new experimental evidence and theoretical advances have been made. Early models were based on limited information and as technology improved, we discovered more about the structure of the atom. Each new model built upon the shortcomings of the previous one, leading to our current understanding based on quantum mechanics.
How did the structure of the atom change over time?
