May 05, 2019 · Key Takeaways: Model of the Atom An atom is a building block of matter that cannot be broken apart using any chemical means. Nuclear reactions can alter atoms. The three parts of the atom are protons (positively charged), neutrons (neutral charge), and electrons (negatively charged). Protons and neutrons form the atomic nucleus.. Thomson's Atomic Model. Matter is defined as everything that takes up space. Air and water, sugar and sand, hydrogen and oxygen etc. all come under matter. Furthermore, the matter is also made up of small particles. Since matter acquires so much space and is a part of our daily lives, it is only natural that one must be keen to observe what. Web.

Model. A model is a representation of a system in the real world. Models help us to understand systems and their properties. For example, an atomic model represents what the structure of an atom could look like, based on what we know about how atoms behave. It is not necessarily a true picture of the exact structure of an atom.
