Ch-03: Atomic Structure
MCQs - Class 9 Chemistry Federal Board
Learn the basics of atomic structure in Unit 3 of Class 9 Federal Board Chemistry. The chapter brief introduces atomic models and the discoveries that helped explain the structure of the atom. It covers subatomic particles—protons, neutrons, and electrons—and explains proton number, relative atomic mass, and the atomic mass unit. Students will also study isotopes, how atoms form positive cations and negative anions, and how to write electronic configurations.
Use the MCQs and short-question answers to review the main concepts and practise for exams.
