Question

Assertion :Metals are good conductor of heat and electricity. Reason: Metals have a free electrons .


A.Both the Assertion and the Reason are correct and the Reason is the correctexplanation of the Assertion

B.The Assertion and the Reason are correct but the Reason is not the correct explanation of the Assertion

C.Our Assertion is true but the Reason is false.

D.The statement of the Assertion is false but the Reason is true. ​

Answer 1

Answer:

Bhai, right answer is (A).

Explanation:

★ Metals is good conductor of electricity and heat because the atoms in the metals from a matrix through which outer electrons can move freely.Instead of orbiting their respective atom,

they form a sea of electrons that surround the positive nuclei of the interacting metal ions.

Answer 2

Answer:

A . Both Assertion and Reason are correct and Reason is correct explanation of Assertion

Explanation:

Metals are good conductors of electricity because of their lower resistivity . Metals have resistivity of the order of 10^-8 to 10^-6 . hence they provide less opposition to the flow of electric charge through them and hence have higher conductivity .
