Elements – Metallic and Non-metallic
Task 1: All the elements in the world are either metals or non-metals and can usually be
distinguished by simple tests.
You will need: samples of elements; a battery (cell); a light bulb and leads and a piece of
emery cloth.
If the bulb lights up the element conducts electricity.
If the element is not shiny rub it with emery paper. It may be shiny underneath. Work
through the samples fill in the table.
