Electrons pass charges through the positive metal ions The sea of electrons helps pass changes Which of the following is not a property of through the metal metals? Shiny luster Metallic bonding occurs between atoms of Brittle/shatters easily Sulfur Conducts electricity Copper Malleable Fluorine Carbon Which of the following is a mixture of elements that have metallic properties The high electrical conductivity of metals is An alloy primarily due to A suspension High ionization energies A gas Full valence shells A pure metal Mobile electrons High electronegativity What does the of electrons” contain? “sea All the electrons in that metal A substance that conducts electricity as a solid The electrons in the outer shell of that and when melted into a liquid is most likely metal classified as The electrons in the inner shell of that An ionic compound metal A molecular compound A metal Why are metals able to conduct electricity? A nonmetal The positive metal ions pass charges to each other Learning Goal 7.4 I can draw Lewis dot – structures for molecules and compounds. Learning Goal 7.5 I can explain polar bonds – and polar molecules in terms of electronegativity; determine the degree of polarity of a bond based on electronegativity, and describe the shape of a molecule based on its polarity.
