1. Z INC -Z N Brenda 7.4

2. G ENERAL I NFO Atomic number: 30 Melting Point: 419.58 C Boiling Point: 907 C Element Classification: Metal

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

4. D ESCRIPTION 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. T HIS IS WHAT Z INC LOOKS LIKE …

6. USES OF Z INC

7. 1. F ORM NUMEROUS ALLOYS Such as… Brass Bronze Nickel Silver Soft Solder German Silver Spring Brass Aluminum Solder

8. 2. M AKE DIE CASTINGS In.. Electrical Automotive Hardware

9. 3. T O GALVANIZE OTHER METALS To prevent corrosion Galvanize means to put coating on iron To make metals stop rusting for quite a long time

10. I NTERESTING F ACTS 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. H AZARDOUS E FFECTS OF Z INC TO THE E NVIRONMENT 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. M ORE INFORMATION ABOUT Z INC In our body, if we dont 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
