Understanding Atomic Theory: Structure and Components of Atoms
This overview of atomic theory explains the fundamental building blocks of matter—atoms. It defines what an atom is, identifies subatomic particles (electrons, protons, and neutrons), and describes their roles within the atom. Protons are positively charged and reside in the nucleus, while neutrons are neutral particles also found in the nucleus. Electrons, which are negatively charged, exist in the electron cloud surrounding the nucleus. This concise guide demystifies the structure of atoms, providing a foundational understanding of matter.
