Answer
Both A and R are true but R is not the correct explanation of A.
Explanation — Metal and alloys (mixtures of metals) conduct electricity using free electrons in their outer shells that move easily in solid state. Hence assertion (A) is true. Non-metals generally do not have free electrons, which is why they are poor conductors of electricity. Hence the reason (R) is true.
However,it does not precisely explain why metals and alloys conduct electricity , the reason (R) only explains why non-metals are poor conductor of electricity. Hence reason (R) is not correct explanation for assertion (A).
