Atoms and Nuclei is a key chapter from modern physics. The JEE Main Atoms and Nuclei Practice Test is a helpful resource for students preparing for the JEE Main entrance exam. It is one of the most scoring topics of the Physics section, and hence, candidates must attempt the JEE Main Atoms and Nuclei Practice Questions with Solutions regularly to yield high scores in the exam. These practice tests will give you an idea of the question paper throughout the years. You will understand the format of questions that appear in the exam from this topic. Atoms and nuclei are a very interesting topic, and they account for about 2 to 3 questions each year in the physics section of the JEE Main entrance exam. So, students must make the most out of it by attempting all the questions asked. These practice tests are important in improving your knowledge of the subject, so that you can answer accurately in the exam. Students can take the JEE Main atoms and nuclei practice test at their preferred time and assess their performance for areas that need improvement.
You will have multiple choice questions, numerical value problems, and assertion-reason questions types asked in the JEE Main exam paper from this chapter. The important topics from atoms and nuclei, from which questions will appear in the exam, are Atomic Models, Radioactivity, Alpha-Particle Scattering, Nuclear Reactions, Nuclear Composition & Size, Nuclear Energy & Stability, and Energy Calculations. The JEE Main Atoms and Nuclei Practice Questions with Solutions are a great tool to practice questions from these topics and master the atoms and nuclei chapter well. These practice test also contain their solutions for the reference of students. These practice tests will enhance the students’ speed and accuracy, which are necessary for success in the JEE Main exam. JEE Main aspirants must solve at least one practice test every week for an effective exam preparation. Also, these practice tests will boost the confidence of the student to answer questions on the exam day.
