This foundational course systematically builds your understanding of chemistry's core principles. Beginning with the mole concept, we explore stoichiometric calculations, percentage composition, and empirical formula determination through practical problem-solving approaches. The law of chemical combinations is taught using real-world analogies that make abstract concepts tangible. We then transition to atomic structure, where students master quantum mechanical models through interactive visualization techniques. The photoelectric effect and Bohr's model are explained using experimental data interpretation. Students learn to write electronic configurations using memory aids for exceptional cases like chromium and copper. Wave-particle duality is demonstrated through mathematical problem-solving of de Broglie's equation. The course emphasizes developing calculation speed for atomic weight determination and isotopic abundance problems - crucial for competitive exams. Weekly sessions include PYQ analysis from the last decade, highlighting pattern recognition in NEET/JEE questions. Special focus is given to overcoming common misconceptions in quantum number assignments through targeted practice drills. You can enroll now.
