Answer:
Calcium-Calcium can be ignited and will when burning react with both oxygen and nitrogen forming calcium oxide, CaO, and calcium nitride, Ca 3 N 2. Calcium reacts readily halogens forming the corresponding dihalides. The reactions with fluorine and chlorine are exothermic while the reactions with bromine and iodine are endothermic.
Aluminium has the ability to displace zinc, iron, copper from their respective salt solutions and therefore is more reactive than them. Zinc has the ability to displace iron, copper from their respective salt solutions and therefore is more reactive than them.
