FAQs on Atoms and Nuclei Mock Test for JEE Main 2025-26: Practice & Solutions
1. What is the difference between an atom and a nucleus?
An atom is the smallest unit of an element that retains the chemical properties of that element, consisting of a central nucleus surrounded by electrons. The nucleus is the dense core at the center of the atom, composed of protons and neutrons, while electrons orbit the nucleus in energy levels.
2. What are isotopes?
Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. This results in different mass numbers for isotopes of a given element. Isotopes have identical chemical properties but may exhibit different physical properties.
3. What is radioactivity and who discovered it?
Radioactivity is the spontaneous emission of particles and energy from unstable atomic nuclei. It was first discovered by Henri Becquerel in 1896, and further researched by scientists such as Marie Curie. Radioactive nuclei emit alpha, beta, or gamma radiation during their decay process.
4. What are alpha, beta, and gamma radiations?
Alpha (α) radiation consists of helium nuclei, beta (β) radiation is made of high-speed electrons or positrons, and gamma (γ) radiation is high-energy electromagnetic waves. These types of nuclear radiation are commonly emitted during radioactive decay.
5. How is half-life defined in nuclear physics?
The half-life of a radioactive substance is the time required for half of the unstable nuclei in a sample to decay. It is a characteristic property of each radioactive isotope and is used to measure the rate of nuclear reactions and dating processes.
6. What is mass defect and binding energy?
Mass defect is the difference between the sum of the masses of individual nucleons and the actual mass of the nucleus. The binding energy is the energy equivalent of this mass deficit, representing the energy required to separate a nucleus into its protons and neutrons.
7. What are the applications of radioisotopes?
Radioisotopes are used in various fields such as:
• Medicine (for cancer treatment and diagnostic imaging)
• Agriculture (to improve crop yield and control pests)
• Industry (for material testing and quality control)
• Research (as tracers to study chemical and biological processes)
8. What is nuclear fission?
Nuclear fission is a process in which a heavy nucleus splits into two or more lighter nuclei, accompanied by the release of a large amount of energy. This process is utilized in nuclear reactors and atomic bombs.
9. What is nuclear fusion and where does it occur naturally?
Nuclear fusion is the process where two light atomic nuclei combine to form a heavier nucleus, releasing tremendous energy. Fusion occurs naturally in stars, including the Sun, where hydrogen nuclei fuse to form helium.
10. What is the importance of the strong nuclear force in the nucleus?
The strong nuclear force is responsible for holding the protons and neutrons together within the nucleus, overcoming the electrostatic repulsion between positively charged protons. It is the fundamental force that ensures nuclear stability.
11. What safety measures are necessary while handling radioactive materials?
Safety measures for radioactive materials include:
• Using proper shielding (like lead containers)
• Maintaining safe distance
• Using protective clothing and gloves
• Limiting exposure time
• Proper disposal of radioactive waste to prevent environmental contamination
12. State the differences between nuclear fission and nuclear fusion.
The key differences between nuclear fission and nuclear fusion are:
• Fission: Splitting of a heavy nucleus; used in nuclear reactors; releases moderate energy.
• Fusion: Joining of light nuclei; occurs in stars; releases energy higher than fission.
• Fission: Produces radioactive waste.
• Fusion: Produces less radioactive waste but is harder to achieve on Earth.
