CHLORINE BROMINE IODINE FLUORINE CARBON SULPHUR 



PHOSPHORUS SILICON BORON TELLURIUM ARSENIC. 



CHLORINE (Cl.) is usually found with sodium in the mineral kingdom, and 

 this chloride of sodium is our common salt. Chlorine can be obtained by 

 heating hydrochloric acid with binoxide of manganese. (Atomic weight 35*5.)
