Metals are very good electricity conductors. Metalloids are half metals, half non- metals which can conduct electricity, but not as good as metals can. Limestone is a sedimentary rock composed largely of the minerals calcite and/or aragonite, which are different crystal forms of calcium carbonate (CaCO3). Therefore, limestone cannot conduct electricity. TheLostJammer
