Non-metallic elements. Clockwise from top left,they are sulphur (S),bromine (Br),phosphorus (P),iodine (I) & carbon (C). Non- metals are poor conductors of both heat & electricity. Sulphur is found in hot springs and volcanoes. Bromine is the only liquid non-metal,it used as a flameproofing agent. Phosphorus is used in safety matches and pyrotechnics. Iodine is added to table salt to counteract deficiency as well as being used in photography. Carbon is used as a fuel (coal) and lubricant (graphite) | |
