The mass of a proton is 1.00728 amu and that of a neutron is 1.00867 amu. what is the binding energy (in j) of a mc006-1.jpgco nucleus? (the mass of a cobalt-60 nucleus is 59.9338 amu.)

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.

if it's not useful, feel free to report for mistake in answer.
