  • Boron - metalloid
  • Potassium - metal
  • Silicon - metalloid
  • Helium - nonmetal
  • Aluminum - metal
  • Hydrogen - nonmetal
  • Calcium - metal
  • Polonium - metalloid

Physical Properties: Possible Answers

Metals:

  • Shiny
  • Solid at room temperature (except for mercury)
  • Malleable
  • Ductile
  • High melting points
  • High densities
  • Large atomic radii
  • Low ionization energies
  • Low electronegativities
  • Good electrical conductors
  • Good thermal conductors

Nonmetals:

  • Dull non-lustrous appearance
  • Poor electrical conductors
  • Poor thermal conductors
  • Nonductile
  • Brittle solid form

Metalloids:

  • Electronegativities between metals and nonmetals
  • Ionization energies between metals and nonmetals
  • Reactivity depends on other elements involved in the reactions
  • Intermediate electrical conductivity (used in semiconductors)
  • Sometimes have characteristics of both metals and nonmetals
