How do you determine the number of electrons?Question 4 options:It is equal to the protons + the atomic numberIt is the atomic mass + the atomic numberIt is equal to the protons in a neutral atomIt is equal to the atomic mass

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.

the correct answer is a. the ability of electrons to flow throughout the metal.
