Interesting Facts
- Lanthanum metal is highly malleable, ductile and sectile.
- If exposed to air Lanthanum metal oxidizes rapidly.
- Zinc metal found (obtain) in many forms like granules, foil, dust and in a powder form.
- The leading producers of Zinc metal are Australia, Canada, China, U.S.A and Peru.
