ZINC-ZNBrenda 7.4

GENERAL INFOAtomic number: 30Melting Point: 419.58 C

Boiling Point: 907 CElement Classification: Metal

DISCOVERYFirst produced in the 1400s in India

Was rediscovered by Andreas Sigismund Marggraf in 1764

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

THIS IS WHAT ZINC LOOKS LIKE…

USES OF ZINC

1. FORM NUMEROUS ALLOYSSuch as…BrassBronzeNickel SilverSoft SolderGerman SilverSpring BrassAluminum Solder

2. MAKE DIE CASTINGSIn..ElectricalAutomotiveHardware

3. TO GALVANIZE OTHER METALSTo prevent corrosionGalvanize means to put coating on iron

To make metals stop rusting for quite a long time

INTERESTING FACTSZinc 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

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

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
