  2. 2 A chemical bond formed by the attraction between positive ions and surrounding mobile electrons is a(n) • nonpolar covalent bond. • polar covalent bond. • ionic bond. • metallic bond.

  3. 6 The electron-sea model of the metallic bond helps to explain why metals are • brittle. • shiny. • dull. • malleable.

  4. 3 A metallic bond forms when positive ions attract • stationary electrons. • cations. • nonvalence electrons. • mobile electrons.

  5. 3 As light strikes the surface of a metal, the electrons in the electron sea • allow the light to pass through. • become attached to particular positive ions. • fall to lower energy levels. • absorb and re-emit the light.

  6. 0 Because metallic bonds permit one plane of ions to slide past another without breaking bonds, metals are • brittle. • nonreflective. • malleable. • poor conductors of electricity.
