Concept:The element required for making matches is one that ignites easily and supports combustion.
Explanation:Sulphur is a non-metal that burns readily in air with a pale blue flame.
It is a key ingredient in the heads of safety and strike-anywhere matches.
When the match is struck, the heat produced ignites the sulphur first.
This helps the match to catch fire steadily and keep burning.
Nitrogen does not burn and is used mainly as an inert filler.
Aluminium is a metal and is not used in match heads for ignition.
Copper is a metal that conducts heat and is not a component of match heads.
Sulphur is therefore the element used in the production of matches.
