Atomic model
The atomic model is a scientific representation of the structure of atoms, the basic building blocks of matter. According to this model, an atom consists of a central nucleus made of positively charged protons and uncharged neutrons, surrounded by negatively charged electrons that orbit the nucleus in different energy levels. This arrangement explains how atoms interact with one another to form molecules and compounds. Over time, various atomic models have evolved, from Dalton's solid spheres to Rutherford's nuclear model and Bohr's planetary model, each improving our understanding of atomic behavior and properties in chemistry and physics.

The atomic model is a scientific representation of the structure of an atom, which is the fundamental building block of matter. Atoms consist of a nucleus at their center, containing protons (positively charged) and neutrons (neutral). Surrounding the nucleus are electrons (negatively charged), which move in regions called electron shells. Various atomic models have been developed over time, from Dalton's solid sphere to Rutherford's nuclear model and Bohr's planetary model, ultimately leading to the more complex quantum mechanical model. Understanding atoms helps explain chemical reactions, the nature of elements, and the properties of materials around us.
