1Step 1: General properties of the metalloids
  • In the periodic table, the metalloids are a group of six elements that divide the metals from the nonmetals.
  • Boron, silicon, germanium, arsenic, antimony, and tellurium are metalloids.
  • These elements have the appearance of metals, but they do not conduct electricity as effectively as metals, hence they are semiconductors.
