Warm Up

Warm Up. Write the formula (remember you need to look at charge!) If you have no idea how to do it, just write the charges for each : Calcium and Fluorine CaF 2 Sodium and Oxygen Na 2 O Magnesium and Sulfur MgS Lithium and Chlorine LiCl Cesium and Iodine CsI.

Presentation Transcript

  1. Warm Up • Write the formula (remember you need to look at charge!) • If you have no idea how to do it, just write the charges for each: • Calcium and Fluorine CaF2 • Sodium and Oxygen Na2O • Magnesium and Sulfur MgS • Lithium and Chlorine LiCl • Cesium and Iodine CsI

  2. Chemistry:Ionic Nomenclature Unit Five, Day One Kimrey 11 October 2012

  3. General Pattern for Ionic compounds • Binary Compounds - Write the name of the first element then write the beginning of the second element plus –ide • Polyatomic compounds – Write the name of the first element plus the name of the polyatomic ion. • Transition metal compounds – Write the name of the first element with the oxidation number (charge) in parenthesis then write the beginning of the second element plus –ide.

  4. Tips • Anions (nonmetal ions) are the element names with –ide at the end. ex. Chloride, oxide, and fluoride • Polyatomic ions never change their names. • Metals not in column 1 or 2 must have roman numerals to show their charge.

  5. Examples

  6. Review • PbF2 Lead (II) Fluoride • CuCl3 Copper (III) Chloride • FePO4 Iron (III) Phosphate • Ni(NO3)2 Nickel (II) Nitrate

  7. Practice • Name The Following • Fe(OH)3 Iron (III) Hydroxide • CoSO4 Cobalt (II) Sulfate • NiF2 Nickel (II) Fluoride • CuNO3 Copper (I) Nitrate • Ca(OH)2 Calcium hydroxide • Write the formulas for… • Manganese (II) Nitrate Mn(NO3)2 • Yttrium (III) Chloride YCl3 • Nickel (II) Sulfate NiSO4 • Magnesium Bromide MgBr2 • Lead (IV) Sulfate Pb(SO4)2

  8. Correct the following Names and write the formula • Magnesium (II) Sulfate Magnesium Sulfate; MgSO4 • Iron dichloride Iron (II) Chloride; FeCl2 • Lead (IV) disulfide Lead (IV) Sulfide; PbS2 • Potassium Hydroxide  ; KOH
