Rhodium is a solid phase of rhodium still unknown to science. The only difference between it and ordinary rhodium is that Rhodium forms a crystal with a bcc unit cell and a lattice constant . Calculate the density of Rhodium . Round your answer to significant digits.

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.
