🔥 What You’ll Learn in This Lecture:
Cracking the atom is the first step to mastering chemistry! This lecture provides a comprehensive understanding of the Structure of the Atom, perfectly aligned with the Class 11th CBSE/ICSE NCERT syllabus and essential for acing your JEE exams. We'll break down the fundamental particles, their properties, and how they arrange themselves to form the building blocks of matter. Build a rock-solid foundation in atomic structure with clear explanations and key concepts you need to know:
• Subatomic particles: Discovery and properties of electrons, protons, and neutrons.
• Atomic models: Rutherford's nuclear model and its limitations.
• Atomic number, mass number, isotopes, isobars, and isotones.
• Electromagnetic radiation, Planck's quantum theory, photoelectric effect.
• Bohr's model for hydrogen atom and its limitations.
• Dual nature of matter, de Broglie relation, Heisenberg uncertainty principle.
• Quantum mechanical model of the atom: Concepts of orbitals and quantum numbers.
• Shapes of s, p, and d orbitals.
• Rules for filling electrons in orbitals: Aufbau principle, Pauli's exclusion principle, Hund's rule.
• Electronic configuration of atoms
