2. Physical Properties of Metals and Nonmetals

  • Metals have luster, malleability, ductility, and sonority.
  • All metals are good conductors of heat and electricity.

3. Chemical Properties of Metals and Nonmetals

  • Metals are reactive. They lose electrons easily and become positively charged ions, so they are electropositive elements.
  • Nonmetals are electronegative elements because they form negatively charged ions by accepting electrons.
  • Metals react with oxygen to form metal oxides.

4. Ionic Compounds

  • Ionic compounds are formed from cations and anions held together by electrostatic attraction.
