Explanation / Answer

1.-4

1.it is chlorine which is cheaper in price

2.it if fluorine which is pale yellow in colour

3.most exothermic is also fluorine because

Enthelpy of atomisation is 79kj/mol which is lowest in halogen

And first ionisation energy is 1681KJ/mol which is highest in halogen

4. Bromine is a red brown liquid
