Unit 5 (bonding & naming) Review You need to use a sheet a paper with this clicker!
1) An unknown black/purple substance is placed in water and the water turns purple after mixing but there are also black chunks at the bottom of the beaker. When the solution is tested with a light bulb (conductivity) apparatus, the light bulb does not light up. What type(s) of bond(s) are present in the substance and explain how you know this. 2) Explain why are substances that contain metallic bonds such good conductors of electricity. 3) Explain why ionic substances cannot conduct electricity when not dissolved in water.
What type of bond and what type of electron interaction occurred in the compound CaCl 2 ? 1.Ionic – Transferred 2.Covalent – Transferred 3.Covalent – Shared 4.Ionic - Shared
