C8h10n4o2 is the chemical formula for caffeine, there are 8 carbons. list the 3 remaining elements in caffeine and how many atoms of that element are present in a molecule of caffeine. (.5pt/element, .5pt/number of atoms)

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.
