In a series of experiments, a chemist prepared three different compounds that contain only iodine and fluorine and determined the mass of each element in each compound: Compund Mass of Iodine Mass of fluorine1 4.75 3.562 7.64 3.433 9.41 9.86Required:a. Calculate the mass of fluorine per gram of iodine in each compound. b. How do the numbers in part (a) support the atomic theory?

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.
