Introduction. The term heavy metal refers to any metallic chemical element that has a relatively high density and is toxic or poisonous at low concentrations. Examples of heavy metals include mercury (Hg), cadmium (Cd), arsenic (As), chromium (Cr), thallium (Tl), and lead (Pb).
Metalloids are those chemical elements that exhibit properties of both metals and non-metals. Since elements with similar properties are placed together in the periodic table, all metalloids are placed together between the metals and non-metals.Metalloid is a term that is derived from the Latin word, metallum which means 'metal', and the Greek word oeides which means 'sort of'.etalloids in the periodic table include Boron (B), Silicon (Si), Germanium (Ge), Arsenic (Ar), Antimony (Sb), and Tellurium (Te). Here are the general physical properties exhibited by metalloids. Refer to the images inside the boxes, for the electronic configuration of each.
