today the most common model is the bohr model. scientist decided to use this because it was a much simpler model and much easier to make. they reaized that by using wire for the different paths of the protons, they would be able to create more models in a less amount of time. thus, the bohr model was created and science projects got much simpler.
It is an inaccurate model, because there is no way to measure the exact mass, path, and charge of an atom
A lot
mass number and atomic number of an atom
J.J. Thomson is credited with the discovery of the electron in about 1904. He envisioned negatively charged "corpuscles" floating in a positively charged cloud, just like plums in a plum pudding. This was the "plum pudding" model of the atom, and it lasted until Geiger and Marsden conducted their gold foil experiment in about 1909.
I believe it was Enrico Fermi, and a number of other scientists.
Niels Bohr.
Today the model of atom is based on quantum mechanics.
they might actually see an atom.
refridgerators
Today the accepted atomic model is quantic.

he used the atom to make a nucluer bomb

You mean elements? So far scientists have brought out some 109 elements. If you mean atom model, then first Prout's model Then Thomson's, Rutherford's, Bohr's, Sommerfeld's. Finally vector atom model.
the scientist behind the concept of the atom are joseph john thomson,goldstein, and james chadwick!
The atomic model of Rutherford was a step in the historical development of the today concept of an atom.
