Atomic model theory describes how atoms are structured and interact. The modern model suggests atoms consist of a nucleus containing protons and neutrons, surrounded by electrons in various energy levels or orbitals. This theory has evolved from early models like Dalton’s solid sphere model to Thomson’s plum pudding model, Rutherford’s nuclear model, and Bohr’s planetary model, culminating in the quantum mechanical model. Understanding atomic structure is crucial for advancements in chemistry, physics, and various technologies.
