The fundamental concept that explains the composition and behavior of matter, including the idea that elements are composed of small, indivisible particles called atoms, and how these atoms interact with each other during chemical reactions
Summary
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 how chemical reactions occur, as these reactions involve the rearrangement of atoms to create new substances while adhering to the law of conservation of mass. Chemical reactions can be classified into various types, including synthesis, decomposition, and combustion. Each type has unique characteristics and applications in the real world, from pharmaceuticals to environmental science. By studying atomic theory and chemical reactions, students gain insights into the building blocks of matter and the processes that govern chemical changes, which are essential for advancements in science and technology.
