What makes metals, in particular, good conductors of electricity? a. the ability of electrons to flow throughout the metal. b. the absence of charged particles. c. the high temperatures required to break metallic bonds. d. the presence of positive and negative ions.

the answer is (A) it allows currents to flow

           Option A is correct.

Explanation:

                     Metals are good conductor of electricity. It has free electrons on their surface. According to Electron Pool Theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form.

         These pool of electrons are free to move and  conduct electricity easily  while making metal as good conductor.
