Using stock system iron has a +3 charge Chloride is in group seven has -1 charge The ions exist in a 1:3 ratio FeCl3ħ Zn3(PO4)2 Zinc Phosphate Metal (Zinc) and a polyatomic ion (Phosphate) Lithium is group 1 so it has +1 charge Fluoride is group 7 so it has a -1 charge Ions are in a 1:1 ratio LiFĦ FeCl3 Iron (III) Chloride Metal (Iron) and a non-metal (chloride) Magnesium is in group two so it has +2 charge Iodide is in group seven so it has -1 charge The ions exist in 1:2 ration MgI2ĥ LiF Lithium Fluoride Metal (lithium) and non-metal (Fluoride) Using stock system iron has a +3 charge Sulfide is in group six has -2 charge The ions exist in a 2:3 ratio Fe2S3Ĥ MgI2 Magnesium Iodide Metal (magnesium) and non-metal (Iodide) Potassium is group 1 so it has +1 charge Bromide is group 7 so it has a -1 charge Ions are in a 1:1 ratio KBrģ Fe2S3 Iron (III) Sulfide Metal (Iron) and a non-metal (sulfide) Presentation on theme: "CaS CALCIUM SULFIDE Metal (calcium), non-metal (sulfide)"- Presentation transcript:ġ CaS CALCIUM SULFIDE Metal (calcium), non-metal (sulfide)Ĭalcium is group 2 so it has +2 charge Sulfide is group 6 so it has a -2 charge Ions are in a 1:1 ratio So the chemical formula is: CaSĢ KBr Potassium Bromide Metal (potassium) and non-metal (Bromide)
