Study Guide Overview

This study guide covers atomic structure, including the internal structure of atoms (protons, neutrons, electrons, ions, isotopes, atomic number, atomic mass), and electron configuration. It also explores the Bohr model, highlighting quantized energy levels, Coulomb's Law, centripetal force, and the standing wave model. Finally, it emphasizes energy level transitions and the emission/absorption of photons.

⚛️ Foundations of Atomic Structure

Internal Structure of Atoms

  • Atoms are not indivisible; they have a complex internal structure. 🔍
  • They consist of a positively charged nucleus at the center, surrounded by negatively charged electrons.
  • The nucleus contains protons (positive charge) and neutrons (no charge).
Key Concept

Nuclear Notation: Represents the number of protons and neutrons. Example: ;612C^{12}_{;6}\text{C} (Carbon-12) has 6 protons and 6 neutrons.

  • Ions form when atoms gain or lose electrons, resulting in a net electric charge.
    • Cations (positive ions) have fewer electrons than protons.
    • Anions (negative ions) have more electrons than protons.
