NCERT Class 11 Chemistry Chapter 2 Structure of Atom Test Mock Test

This free online test covers Chapter 2, Structure of Atom, from the NCERT Class 11 Chemistry Part I textbook. The 30 questions are written directly from the chapter — definitions, processes, worked examples and the points the book italicises — so a score here tells you how much of the chapter actually stuck, not how well you guess. Each answer carries an explanation that says why the right option is right and why the other three fail, which is where most of the learning happens. Attempt it after your first read of the chapter, then again before the exam. There is no negative marking, and you can review the full solution the moment you submit.

Sample Questions

Q1.The observation that finally established the electron as a basic constituent of all atoms was that the characteristics of cathode rays:

  • ADo not depend upon the material of the electrodes or the nature of the gas present in the tube
  • BDepend on the pressure to which the discharge tube has been evacuated
  • CAre observed only when the gas in the tube is hydrogen
  • DChange sharply when the cathode is made of a different metal

Q2.Thomson's measurement of the charge to mass ratio of the electron gave the value:

  • A1.602176 x 10^-19 C per kg
  • B6.626 x 10^-34 C per kg
  • C9.1094 x 10^-31 C per kg
  • D1.758820 x 10^11 C per kg

Q3.In Millikan's oil drop experiment, the conclusion drawn from measuring the charge on many droplets was that the charge q on a droplet is:

  • AProportional to the mass of the oil droplet
  • BContinuously variable, taking any value between zero and a maximum
  • CAlways an integral multiple of the electrical charge e, that is q = ne where n = 1, 2, 3
  • DThe same on every droplet regardless of how it was produced
