Statement A : Isotopes of an element can be seperated by using a mass spectrometer. Statement B : Separation of isotopes is possible because of difference in mass number of isotopes.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
A mass spectrometer ionizes atoms with a high energy electron beam and then deflects the ions through a magnetic field based on their mass to charge ratio. So option (3) is correct.

If the mass number of an atom is \(A=40\) and its electron configuration is \(1 {~s}^{2}, 2 {~s}^{2}, 2 {p}^{6}, 3 {~s}^{2}, 3 {p}^{6}\), then let \({N}\) be the number of neutrons and \({P}\) be the number of protons in its nucleus respectively. Find \(2 {P}+3 {~N}\).

Explanation:
Number of protons \((P)\) \( = 2 + 2 + 6 + 2 + 6 = 18\) Number of neutrons \(({N})=40-18=22\) \(\therefore \quad 2P + 3N = 36 + 66 = 102\)

A free neutron decays into a proton but a free proton does not decay into neutron. This is because
1 neutron is an uncharged particle
2 neutron has larger rest mass than proton
3 neutron is a composite particle made of a proton and an electron
4 proton is a charged particle
Explanation:
The transformation of a free proton to a neutron in terms of charge is impossible, since a free neutron has a larger rest mass than a proton. So, correct option is (2).

Assertion : For the scattering of \(\alpha\) -particles at large angles, the nucleus of the atom is responsible. Reason : Neutrons and protons in nucleus are bound by strong interaction.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Electrons are significantly lighter than \(\alpha\) particles. Therefore, electrons cannot scatter \(\alpha\) particles at large angles, in accordance with the law of conservation of momentum. In contrast, the mass of the atomic nucleus is comparable to that of the \(\alpha\)-particle, which is why the nucleus alone is responsible for the scattering of \(\alpha\)-particles. Reason is separate fact. So correct option is (2).
