There are many, but here are the main ones:
1) Dalton's Billiard Ball Model
2) Thompson's Plum Pudding Model
3) Lewis's Cubical Atom Model
4) Rutherford's Planetary Model
5) Bohr's Model
6) Schrodinger's Electron Cloud Model
its are dalton's,thompson's,rutherford's,bohr'sand quantummechanical models that's all folks
by looking at them through electron microscopes
Atoms are the building blocks of all matter
You don't really know what it looks like. What's more, an individual atom doesn't "look like", because it is much smaller than the wavelength of visible light. What the models used to describe the atom really say is that the atom "behaves as if..." such-and-such.
The conclusion is that the positive charges in an atom are concentrated in a fairly small space, now known as the nucleus.
Atomic models tell us about the structure of an atom which is based on what we know about how atoms behave. But it is not necessary that it will be a genuine picture of the structure of an atom.

Isotopes and Electrons
A model of the atom is a 3-D structure of the atom's structure.

The plum pudding model of an atom has not a nucleus; in 1904 the nucleus, protons, neutrons were not discovered. See the link below.
An atom is a neutral structure consisting of a single nucleus with its orbiting electrons. A cation is a positively charged structure consisting of a single nucleus with its orbiting electrons. The major difference between an atom and a cation is that the cation has lost one or more electrons and therefore has a positive charge overall.
Models of atom are not perfect since they exhibit more features which are not present in model.Hence, an improvement is always required.
There is none because there are no bonds in an atom.
What was proven wrong about the structure of Niels Bohr atom
When the models are not shown a person will not be able to know if there are any hydrogen atoms between them. If the models are shown a person will be able to know the answer.
The atomic structure dictates how easily the atom can bond with another atom. It also dictates the charge that an atom has.
