well, lots of scientists discovered different parts of atoms. The scientist who discovered atoms was called dimeter, then, there where lots of other parts of atoms, such as Tomson, Bohr...
Size, if a model of an atom was in proportion, the electrons would be very far away from the nucleus
It was dropped on Nagasaki.

It's difficult to predict, isn't it, because we cannot predict what that new information might prove to be.
A model of the atom is a 3-D structure of the atom's structure.
The best model to describe atomic structure is the Rutherford model

In a neutral atom, the number of electrons is the same as the number of protons. The electronic structure of an atom with five electrons would be 2, 3. The electron configuration would be 1s22s22p1.
