Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : Radioactive nuclei emits ( ⁻ ) particle. Reason (R) : Electrons exist inside the nucleus In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A).
- BBoth (A) and (R) are true and (R) is NOT the correct explanation of (A).
- C(A) is true but (R) is false.
- D(A) is false but (R) is true.
Correct answer
C. (A) is true but (R) is false.
Step-by-step solution
Assertion (A) states: "Radioactive nuclei emits ( )-particle." This statement is true. Reason (R) states: "Electrons exist inside the nucleus." This statement is false. Electrons do not exist inside the nucleus; they are produced during beta decay from the conversion of a neutron into a proton. Therefore, (A) is true but (R) is false. This corresponds to option (3).
