What BEST compares the properties of ionic and metallic substances? Group of answer choicesThe bonds of metallic substances are composed of delocalized electrons, and the bonds of ionic substances are composed of transferred electronsThe bonds of metallic substances are composed of ioslated electron, and the bonds of ionic submstances are composed of shared electrons.A metallic substance insulates heat and electricity, and solid ionic substances conduct heat and electricity.A metallic substance has a low melting point, and an ionic substance has a low melting point
