This task is about testing elements to see if the are metal or non-metal.
Carry out a series of tests on the elements listed below to find out if they are a metal, or a non-metal. Elements to be tested; magnesium (Mg), calcium (Ca), carbon (C), sulfur (S), zinc (Zn), copper (Cu), iodine (I), and aluminium (Al). You will need to carry out tests for; lustre, electrical conductivity, malleability.
The melting point of these elements has been put in the table.
Tests:
- Malleability – does it bend or can it be beaten into shape?
- Electrical conductivity – set up a simple circuit using a cell, wires, and bulb.
- Lustre – does it shine when it is scratched or sanded?
