“Heavy Metal Elements”  

Heavy Metals

  In chemistry, Heavy Metals, as toxic metals, are trace metals with a density at least five times that of water. With this density they are stable elements (meaning they cannot be metabolized by the body) and bio-accumulative (passed up the food chain to our bodies).
  In chemistry, the Heavy Metals, form colored salts and double salts, have a low electrode potential, are mainly amphoteric, yield both weak bases and weak acids, and are oxidizing or reducing agents.
  Examples of heavy metal elements include:

actinium (Ac) americium (Am) antimony (Sb) barium (Ba) berkelium (Bk) bismuth (Bi) cadmium (Cd)

cesium (Cs) cobalt (Co) chromium (Cr) copper (Cu) einsteinium (Es) iridium (Ir) iron (Fe)

lawrencium (Lr) lead (Pb) mercury (Hg) molybdenum (Mo) niobium (Nb) radium (Ra) silver (Ag)

technetium (Tc) tungsten (W) uranium (U) vanadium (V) zinc (Zn) zirconium (Zr)
