Overview
Atomic theory is a fundamental concept in chemistry that explains how matter is composed of atoms. Each atom consists of protons, neutrons, and electrons, and the way these atoms interact through chemical bonds leads to the formation of molecules. Understanding atomic theory is crucial for grasping ...
