What is the name and symbol of your element? Zinc; Zn
Who discovered it? Andreas Marggraf
What year was it discovered? 1746
How abundant is it on earth?
Is it a solid, liquid or gas at room temperature? solid
Is it metallic or non metallic? metallic
What is its melting & boiling points? Melting point: 419.58 °C
Boiling point: 907.0 °C
Is it toxic or dangerous in any way? Zinc fumes can be toxic for people who work with the metal
while it's heated, and free ions of zinc can be very dangerous. Zinc fumes at normal melting and
casting temperatures are not unsafe. No ventilation is required. I know nothing about ions but if
zinc is overheated and the oxide is inhaled for long periods, this can make you sick (zinc shakes
or zinc fever)
What is its normal color? Bluish gray
What is its atomic mass? 65.39
Name 5 elements that it reacts with to make compounds; Oxide, Hydride, Chloride
Name 5 practical uses for this element; Zinc metal is used for dry batteries, roof cladding, and to
protect iron structures from corrosion by attaching zinc as sacrificial anodes. Zinc metal is also
used in lightweight coins (for instance, USA and Canadian one cent coins are zinc coated with
bronze plate). A large proportion of all zinc, perhaps more than a third, is used to galvanize
metals such as iron so as to prevent corrosion.
