The book has a dedicated section called "NCERT FILE" at the end of each chapter. This section contains fully solved solutions to all in-text questions, exercise questions, and NCERT exemplar problems.
Building on the previous chapter, this one takes you inside the atom. It chronicles the discovery of subatomic particles—electrons, protons, and neutrons. You will explore the historical development of atomic models, including Thomson's model, Rutherford's model (and his famous gold foil experiment), and ultimately, Bohr's model of the atom. The chapter concludes with concepts of atomic number, mass number, isotopes, and isobars. The diagrams and historical anecdotes in "Modern ABC" help bring these abstract concepts to life, making it easier to remember the contributions of different scientists.
