LEARNING OBJECTIVES

  • Describe the evidence that supports the idea that the simple particles have a property we call charge.
  • Describe the evidence that led Thomson to suggest that the mobile charge in atoms is negative.
  • Use the Thomson model of the atom to account for the fact that neutral atoms can become either positively or negatively charged by the loss or gain of electrons.
  • Identify properties that distinguish metals from non-metals.
  • Describe the evidence that distinguishes ionic from molecular or atomic solids.
  • Given the formula of an ionic or molecular substance, state its name.
  • Given the name of ionic or molecular substance, write its formula.
  • From the name or formula of a substance determine whether that substance is ionic or molecular.
