JEE Advanced Important Questions of Nuclear Chemistry

In this chapter, you will learn about alpha rays, beta rays and gamma rays and also their charges when they are bent towards negative plates and positive plates. You will also learn that uncharged radiations will pass in a straight line through the electric field. The main topics in this chapter are Alpha particle or Alpha Decay, Beta particle or Beta Decay, Gamma Radiation and Transmutation.


This is one of the shortest units under physical chemistry which has a weightage of 5% in the final examination which is approximately 4 marks.

Nuclear Chemistry Important Questions for JEE Advanced

Nuclear Chemistry JEE Advanced Important Questions deals with the study of how atoms are combined into molecules. The word "nuclear" in this field means that it deals with the nucleus of an atom and not just electrons. This branch of chemistry deals with what happens when you try to break apart these molecules- for instance, when you put them under pressure or heat them up through a chemical reaction.


In the JEE Advanced exam, a good understanding of Nuclear Chemistry is essential to answer all the questions. So, we provide an insight into important questions from this subject that will help you practice well before appearing for the JEE Advanced exam.


JEE Advanced Important Formulas for Nuclear Chemistry

Nuclear chemistry is a branch of chemistry that deals with the study of nuclear processes, including nuclear reactions and properties of radionuclides. Here are five important formulas in nuclear chemistry that may be useful for JEE Advanced:


Decay Law:

$N(t) = N_0 \times e^{-\lambda t}$


Where:

N(t) is the quantity of radioactive substance at time 

$N_0$ is the initial quantity of radioactive substance,

λ is the decay constant, and

e is the base of the natural logarithm.


Half-Life (T½):

$T_{\frac{1}{2}} = \frac{\ln 2}{\lambda}$


Where:

$T_{\frac{1}{2}}$ is the half-life of the radioactive substance.


Binding Energy (E):

$E = \Delta m \times c^2$


Where:

Δm is the mass defect (mass difference between the nucleus and its individual nucleons),

c is the speed of light.


Nuclear Reaction Energy (Q-value):

$Q = (\text{Mass of reactants}) - (\text{Mass of products})$


For a nuclear reaction aA + bB → cC + dD

Where a,b,c,d are coefficients.


Rutherford Scattering Formula:

$\frac{1}{\tan(\frac{\theta}{2})^2} = \frac{4Z_1 Z_2 e^2}{\pi \varepsilon_0 mv^2 b}$


Where:

θ is the scattering angle,

$Z_1, Z_2$ are the atomic numbers of the incident and target nuclei,

e is the elementary charge,

$\epsilon_0$​ is the permittivity of free space,

m is the mass of the incident particle,

v is the velocity of the incident particle,

b is the impact parameter.


Types of Important Questions from Nuclear Chemistry in JEE Advanced:

Most questions asked in JEE Advanced from this topic can be classified into the following types:


Nuclear Equations: In these questions, you are given the reactants and products of a nuclear reaction and asked to write the equation for the reaction.


One such example is: The question asks for the balanced equation for the radioactive decay of uranium-235. The balanced equation for the reaction is: uranium-235 → thorium-231 + a proton


Isotopes and Ions: In these questions, you are given an atom or molecule with one or more isotopes and asked to identify them by using mass number, atomic number, and their chemical properties.


For example :The question asks for the isotope of carbon, which has an atomic mass number 12. The correct option is "carbon-12".


Mass Spectrometry: In these questions, you are given a compound and its molecular formula along with some peaks from a mass spectrum and asked to identify the different elements present in it by using their masses.


For example : The question asks for the element, which is present in a molecule of molecular formula CH. The correct option here is "carbon".


Nuclear Reactions: In these questions, you are given some reactions and asked to identify whether they can be used as nuclear reactors or not by considering their application. 


For example : In this case, the reaction cannot be used as a nuclear reactor because it doesn't have the required features.


Nuclear Fission: In these questions, you are given some data about a fission reaction and asked to identify its products.


For example : The question asks for the products of the fission reaction between uranium-235 and neutrons. The products of the reaction are uranium-236, barium-140 and krypton-89.


Nuclear Fusion: In these questions, you are given some data about a fusion reaction and asked to identify its products.


For example : The question asks for the products of the fusion reaction between deuterium and tritium. The products of the reaction are helium-three and a neutron.

By understanding these types of questions, you will be able to practice well and score good marks in the JEE Advanced Nuclear Chemistry paper.
