Question and options
Direction: Two statements are labelled as Assertion and Reason. In the context of the two statements, which of the following is correct?
Assertion: All metals conduct electricity
Reason: Electrons are free to move within the atomic structure of metals
Assertion: All metals conduct electricity
Reason: Electrons are free to move within the atomic structure of metals
- Both the assertion and reason are true, and the reason is the correct explanation of the assertion
- Both the assertion and reason are true, but the reason is not the correct explanation of the assertion
- The assertion is true, but the reason is false
- The assertion is false, but the reason is true
Answer and explanation
Correct answer: A - Both the assertion and reason are true, and the reason is the correct explanation of the assertion
Metals conduct electricity because their valence electrons are delocalised and free to move through the lattice. Both statements are true, and the free movement of electrons is exactly why metals conduct, so the reason explains the assertion.
