Assertion & Reason Analysis
This question requires evaluating two statements about the electrical conductivity of metals.
Statement Analysis
- Assertion (A): States that "All metals are good conductors of electricity."
- Reason (R): States that "Metals contain free electrons that allow electric current to pass."
Evaluating Statement (A)
The provided answer indicates that Assertion (A) is not correct. While most metals are indeed excellent conductors, the absolute statement "All metals are good conductors" might be considered incorrect in certain contexts or due to specific exceptions not typically emphasized.
Evaluating Statement (R)
Reason (R) correctly explains the fundamental reason for electrical conductivity in metals. Metals possess a lattice structure where valence electrons are delocalized, forming a "sea of electrons." These free electrons are mobile and can easily move when an electric field is applied, thus carrying electric current.
Conclusion
Based on the provided correct answer:
- Assertion (A) is deemed incorrect.
- Reason (R) is deemed correct.
Since Assertion (A) is incorrect, Reason (R), even though correct, cannot be its correct explanation. Therefore, the situation aligns with (A) being incorrect and (R) being correct.
