Answer :
Let's address each question one by one and provide explanations for the answers based on the provided information and results.
35. Alpha Particle Scattering Conclusion:
When alpha particles were sent through a thin metal foil, it was observed that only a small fraction rebounded. This led to significant conclusions about atomic structure:
- Since only a few particles deflected, it indicates that most of an atom's mass and its positive charge are concentrated in a small region, known as the nucleus.
Therefore, the correct conclusion is:
a. Positively charged particles are concentrated at the centre of the atom.
36. Canal Ray Experiment Discovery:
The canal ray experiment, which involved observing positive rays in gas discharge tubes, led to the discovery of:
a. protons
37. Energy Difference Between Shells:
The energy difference between two adjacent orbits (shells) is minimum between shells that are further from the nucleus:
b. [tex]\( L, M \)[/tex]
38. Assertion and Reasoning:
- Assertion A claims that electrons in inner orbits are more tightly bound to the nucleus.
- Reason B explains that a more negative electron energy value indicates stronger binding.
Both statements are correct, and reason B correctly explains assertion A:
b. Both [tex]\( A \)[/tex] and [tex]\( B \)[/tex] are individually correct and [tex]\( B \)[/tex] is the correct reason for [tex]\( A \)[/tex].
39. Isotope Composition of Element with Isotopes [tex]\(_7^{15}X\)[/tex] and [tex]\(_7^{11}X\)[/tex]:
Given that the average atomic weight is 14, the percentage composition of each isotope is:
75% for [tex]\(_7^{15}X\)[/tex] and 25% for [tex]\(_7^{11}X\)[/tex].
So the answer is:
c. 75, 25
40. Isotope Composition of Element with Isotopes with Mass Numbers 16 and 18:
The average atomic weight is 16.5, which corresponds to:
75% for the isotope with mass number 16 and 25% for the isotope with mass number 18.
So the answer is:
a. 75, 25
41. Identification of Isobars:
Isobars are atoms of different elements with the same mass number but different atomic numbers. The correct pair is:
d. [tex]\({ }_b^a X ,{ }_{b-1}^{a-1} Y\)[/tex]
42. Reason for Fractional Atomic Masses:
Fractional atomic masses can be explained by:
b. the existence of isotopes.
By considering isotopes with different masses, the average atomic mass can become a fraction due to the mixture.
