This is not really a question. If you want to build an animated version of an atom then there are plenty of websites out there. If you want to build a physical model you could use anything from Styrofoam balls to jelly beans.
There are not rules that you must follow in order to build a model of the Mayflower. You literally make up your own limits.
John Dalton was the one who invented atom model. Thomson, Rutherford, Bohr and de Broglie also helped him build it.
A model of the atom is a 3-D structure of the atom's structure.
This is the quantic model of atom.
The Bohr model of the atom was a planetary model.
To build a model of an ionized atom, you would start with a neutral atom and then remove one or more electrons, resulting in a positively charged ion. If an atom becomes too ionized, it may lose its stability and react more readily with other atoms or molecules. For a radioactive model, you would depict an unstable nucleus with an imbalance of protons and neutrons; this could be represented by showing excess energy or particles being emitted. If the imbalance becomes too great, the atom may undergo radioactive decay, leading to the emission of radiation and transformation into another element or isotope.
See links below for a variety of options for building your own model of the solar system.
Ernest Rutherford is perhaps best known for his model of the atom. He developed his own model, based upon his research, to replace Thomson's plum-pudding model.
You can also use paint and create it on your own.
Today the model of atom is based on quantum mechanics.
A Millikan atom model doesn't exist.
A model of the atom is a 3-D structure of the atom's structure.
