Day 12: Atoms | Class 12 Physics 60 Days Challenge 🎯 ​Welcome back to Day 12 of our 60 Days CBSE Board Exam Challenge! Today, we are zooming into the microscopic world with Chapter 12: Atoms. ​This chapter is the bridge between Dual Nature and Nuclei. We will explore how our understanding of the atom evolved—from Rutherford’s "planetary" model to Bohr’s revolutionary postulates. Understanding these concepts is crucial for securing full marks in the Modern Physics section! ​📚 Key Topics Covered: ​Alpha-particle Scattering Experiment: Understanding the nucleus and distance of closest approach. ​Rutherford’s Model: Successes and its major drawbacks. ​Bohr’s Model of the Hydrogen Atom: The three famous postulates. ​Energy Levels: Calculating the radius (r_n), velocity (v_n), and total energy (E_n) of an electron. ​Hydrogen Spectrum: Mastery of the Lyman, Balmer, Paschen, Brackett, and Pfund series.
