Atom and the Periodic System
Learning Time: 4-12 hours
Content: Atom and the Periodic System is a fundamental subject that examines the structure of the atom and the organized classification of the elements. This area covers the subparticles of the atom (proton, neutron, electron), atomic structure models (Bohr, quantum model), the formation of the periodic table (Mendeleev’s contributions), periodic properties (atomic radius, ionization energy), and the modern periodic table. The TYT exam focuses on atomic structure and periodic trends, while the AYT exam focuses on chemical bonding and transition elements. The current 2025 curriculum also highlights synthetic elements and materials science applications. Learning this topic provides a critical foundation for understanding the behavior of the elements.
