  1. Zinc-Zn Brenda 7.4

  2. General Info • Atomic number: 30 • Melting Point: 419.58 C • Boiling Point: 907 C • Element Classification: Metal

  3. Discovery • First produced in the 1400s in India • Was rediscovered by Andreas Sigismund Marggraf in 1764

  4. Description • It is a soft metal • It a has grayish or blue-white color • It contains 21 isotopes where 5 of them is stable and the other 16 are not (unstable) • It is brittle at low temperatures but malleable at 100-150 C • It is an electric conductor • It burns in air at high red heat

  5. This is what Zinc looks like…

  6. uses of Zinc

  7. 1. Form numerous alloys Such as… • Brass • Bronze • Nickel Silver • Soft Solder • German Silver • Spring Brass • Aluminum Solder

  8. 2. Make die castings In.. • Electrical • Automotive • Hardware

  9. 3. To galvanize other metals • To prevent corrosion • Galvanize means to put coating on iron • To make metals stop rusting for quite a long time

  10. Interesting Facts Zinc is.. • Found on roofs because it has a very high quality of roofing material • A metal we all need for life • Part of enzymes and many biological medicated processes • Easily reacted with acids to produce hydrogen • Very slow to oxidize • An interesting element because it is not a poisonous element, where the two other elements that are in the same group with Zinc, Mercury and Cadmium, are both pretty poisonous. • Something we need for us to survive

  11. Hazardous Effects of Zinc to the Environment Zinc production can cause: • Water pollution-it can cause for fish to be accumulated with Zinc which is able to bio magnify up the food chain • Soil pollution-farmlands could be polluted which can cause farm animals to absorb concentration that damages their health. It could also break down microorganisms and earthworms since their habitats are polluted. • Plants to have their system unstable, unhandled and uncontrolled

  12. More information about Zinc • In our body, if we don’t have enough Zinc, we are not able to smell things. • When you combine it with other elements, it could get quite frisky • Zinc is an abundant metal • An enzyme called ‘Carbonic Anhydrase’ needs Zinc to catalyze the reaction of CO2 and water
